Wedding Venue nightmare - sos

I truly hope that no one has had to deal with this butttt, I'm here looking for anyone with a similar experience and their guidance.

We toured a venue back in Dec 2017 and signed the contract in May 2018 due to the venue being closed for the beginning months of the year... Wedding is Summer 2020. I heard through the wedding grapevine in my area that the venue had fired their coordinator, who played a very large part in our selection.

I called the venue to confirm and a month and several calls and emails later I found out this was true. The previous coordinator had verbally promised us several things that we are now not getting. Most importantly, the fact that our initial deposit was just that, a deposit, and that we were locked into the 2017 pricing, as that was all that available at the time of signing.

Now, we are being told that the deposit is a room rental fee and that we are not locked into any pricing and must use the most up to date pricing, which is several thousands of dollars more. The contact we signed does not mention the pricing guide, but does state that the deposit will be credited towards the final bill. Other paperwork that we were given, but did not sign, mentioned that the "deposit" was to go towards the rental of the room, and the previous coordinator confirmed that it was not a room rental fee. The wording is confusing, thus why I asked for clarification. The two documents are contradictory.

Now, we are looking about $10k on top of the initial price... for the same stuff. Less, actually. Anyone ever have any issues like this? Do I seek legal help regarding the contract? Not sure what to do as we can't be giving up the venue at this point and need to make it as easy as possible to work with the venue. SOS!!!
