Would love if anyone else has insights on how to dispute that. 

Mediation is a process in which the parties meet with an impartial person who helps to resolve the dispute informally and confidentially.

My involvement in this dispute of deposit money began and ended in those screenshots I supplied.

Any goals or resolutions anyone wants to share? 

So I disputed the additional charge. 

Hey Tyler we hate to hear that your experience was negative sincerely we would have hoped that we could have come to a resolution we know that you and your partner had made a request that we do $800 of work that was unfortunately not in your scope of work at the time we had exhausted $4900 in additional work to ensure the property was to satisfaction which included a new hood range upgraded lvp flooring additional framing  new window and a paint upgrade from a single color format to a multi color format and can lighting all of which was never in the original scope and unfortunately when we requested that we do the work you declined I’ve attached before and after videos of the home for reference https://www.dropbox.com/scl/fi/h0ddll4cyp5g5gq12o73s/Video-J... always twos sides to these stories.. 

It's a good idea to consult with a real estate attorney to ensure everything is legally binding and clear to avoid future disputes.

Not disputing your experience and I'm sure your agent is great.However, the Goosehead model is designed for the local agent to sell and the corporation to service.

This friend and I have done 2–3 deals together, and there’s never been a payment dispute or even a hint of cutting him out of something.

@Steve Mitrano this thread got bumped up in my feed and looks like you found a resolution but just to add.
