Title Company Holding Up Closing - Is this allowed?

[Shelby Crowder]

We have an on market wholesale deal with an addendum for closing to be yesterday, that was signed by all parties. Unfortunately the seller was set on a specific title company, as was the buyer for a different title company. We thought everything was going smoothly until we got a message day of closing that seller’s closer at their title company was not even working that day. So we were annoyed but whatever, until we called today and she refuses to schedule closing or tell us any idea of when she plans on scheduling it. We know that everything came back good on title and its ready, but this closer won’t schedule it and honestly seems like she’ll just keep doing it to annoy us. Is the closing addendum in the contract legally enforceable to a title company? Or what can we do to get this deal closed?
