Title company calculated my taxes credited wrong

[Brad Ingram]

Hi - Wondering what can do now.  I just sold/closed on my house on Thursday (7/2/2020), so the deal is final.  This morning, I was looking at my mortgage payoff and while looking at things in more detail, I noticed that the title company calculated my credit for the taxes (county and school) that i have already paid incorrectly.  Looks to be around $500-$600.  What can i do to try to recoup this money?  Really appreciate any insight and guidance on what course of actions i could take.

Thanks
