Mortgage escrow has been paying wrong account for my property Tax

[Allen Hua]

I am currently living in CA, invested in a townhouse with my wife in 2017 in the Seattle downtown area, currently occupied by renters.   We are currently in the process of looking into refinancing for this property when we found out that our mortgage escrow company has been mistakenly making tax payments from our mortgage escrow to a wrong tax account for 2 years, and it seems like the wrong tax account owner got refunds from the county already. We are working to correct the error with the escrow company ASAP. It will be very helpful if someone can provide us some guidance about how to correct this kind of mistake. I never faced this kind of problem in my life, this is a very stressful situation, hope you can give me some information and help. Do I need to talk to a real estate lawyer? Thanks ahead.
