How do i request refund from my wedding planner, after my wedding?

We hired a wedding planner from wedding wire 6-8 months before our wedding date. We interviewed several from the app that had responded to our inquiry. This one stood out particularly because it seemed like she “just got us”. We wanted a Halloween wedding but not the typical ghouls and goblins. We wanted a gothic masquerade wedding, mix of dark romance and 50 shades of grey. The service that was offered was “full service”. Meaning the planner would handle everything from research to production. Aside from paying each vendor. That seemed perfect for us due to our work schedules. We explained in the initial conversation that I am (bride) very indecisive and only want to be able to give an explanation of what color style etc. and have only three option presented for final decisions. Now I know this sounds far reaching but I will stay on a topic for way too long day and night trying to find the perfect whatever. There was no problem with the planner on this aspect. Well that never happened. Another thing we were glad about was the fact of payment arrangements instead of up front total. In all, with all the services offered and promised, we were not supposed to do anything but make final decisions from the three options in each aspect of the wedding, make payments to those chosen vendors and show up when needed. We paid almost $5,000 just for the planner. At first, during the first couple of payments everything was fine. Contact and communication between us was on point. Until it came time for decisions to be made, and requests were made from us to the planner on specifics that weren’t produced. There were a few times I would send an email asking for specific information on decor and other things that would not get a reply until a week or so later, not even addressing the issue but simply saying “I understand your concerns, don’t worry about those things I’ll take care of them” or “I will email you those things shortly” and never get the email. Things were progressively getting worse and at one point we consulted with another planner what our issues were and were told by several people that this planner was taking us for our money and there was no reason for the amount we were paying, just to have to do all the work ourselves. We were about 45 days to our date and had not even discussed a caterer. There was no help from our planner in any of the details that were promised. Contract and logistics were also to be handled by the planner and made sure they were legit. The only contract that was reviewed was the one from the venue. Looking back I now understand why that one was so important for her, because there were 99% of the decor was in that contract. Which was important bc the planner was to charge separately from her $5000 for the decor. I sent her several numbers for other vendors to contact to review contracts. I had to do all the research for each vendor and send her the information. I had to send pictures of the type of decor we wanted, which by the way wasn’t much considering we wanted to us the natural look of the venue we had chosen. I had to request several times for the budget because that too was to be handled and could not get any straight replies. So we didn’t know how much money we could set aside for our big day. We sent her a detailed email explaining our concerns and requesting one final time specific information and pointed out each thing that was incorrect. Such as the theme of our wedding, the date and time she had wrong. Along with other things. We at one point about 40 days before the wedding finally were fed up with no responses and so many details lacking, let her go. We sent a long email explaining in detail the areas of the contract she had failed to produce and requested our money back from her then. It wasn’t until then when she finally answered the previous email about our concerns. Not even addressing the fact of the email firing her. Which was extremely odd. Finally almost a week later we were able to speak cia phone with her, she explained at that point she had an assistant that she allowed to handle our event that was not very efficient. And because of that assistant and the mistakes that person made, she was no longer allowing her to handle our event and because of the stress that was caused she was going to be adjusting our contract and the remaining balance including the decor price in lieu of us being upset and firing her. So we kept her thinking she would fix what had been messed up and overlooked. Boy was that the worst mistake we made. The decor she promised was not what she promised, my flowers and bouquets for the wedding party she refused to show me and were not ready until my girls and I walked down the aisle. She was more concerned with what her 8yr old was doing than the details involved with the day of coordinating. She was extremely rude to not only my wedding party but to the guests that had arrived, causing them to leave before we were even able to cut the cake. She cut our cake for us, insisted we only hold it in position for pictures, then rudely stepped in to cut it for us and place it onto a napkin. She didn’t send the information containing alcohol license and insurance to the vendor causing us to not be able to serve beer and wine, bc her child was present. One of my guest over heard her and the venue owner discussing the fact and she stated she didn’t want her daughter around alcohol anyways so she wasn’t worried about the logistics on that. Which absolutely pissed me off during my wedding. There were so many details she left out that some would say might be petty, but these details were what brought everything together and I’m not sure if she intentionally left them out or if she really didn’t know what she was doing. She was supposed to have her “team” on the day of but it was only her and her 8yr old. At that point she was paid in full for her services that clearly she had not produced as promised. Now here we are almost a month after our date and I’m finally calmed to the point of asking assistance without reacting solely on emotions. She never adjusted her contract price and is now requesting another $1000 for decor and the only decor she provided was grocery store flowers that were completely wrong from what was discussed and promised. And I understand now why I wasn’t able to see them until right as I was about to walk sown the aisle. Any advise or direction from anyone who knows what my options are would be great. I am also sending this to admins of WeddingWire bc we hired her through them and on social media for advice from others in the industry without naming names but being as specific as possible. TIA.
