i Just Wanna Pay My Bill...

I'm trying to officially check off my photobooth vendor and I'm SO FRUSTRATED. They're supposedly one of the best photographers in the area... but I'm super glad I only got the photobooth from them.

They sent me photobooth backgrounds. I chose one and requested 2 changes. They made one change. I said I like it but what about the other change. He told me they would make it but no more changes would be made after that unless I paid a $60/hr design fee. Literally, no big. I get it, but don't come at me like I'm being a pain, when I specified it to begin with. Got that change made.
I asked for an invoice for the remaining balance. It has my preliminary info on it. We had a place in mind, but if didnt work out. I sent him the new info as soon as I booked our venue 11 months ago.There's no link to pay, and no address to send a check...So I sent an email. With all the updated information. Asked them to confirm and send me a link to pay...Silence for the last 36 hours...Seriously!?! I want to pay you and leave you alone for 4 weeks. If I'm as big of a pain as you're pretending I am, you should be on board with the plan.I feel like one of the biggest pains of this whole wedding has been paying Bill's. Not due to lack of money, but because people just won't take it.Blargh.
