Prosperity Abstract in 36 N 3rd st Philadelphia, PA review: Title company collected escrow money taking for bills never but never paid those bills

I sold my property in 1131 bridge street and Prosperity Abstract in 36 N 3rd Philadelphia PA was the title company chosen to close, my son and daughter had my name on their property that was not in judgement collection. They insisted to keep escrow collateral for total to almost $11,000 even dough those property is not sold. I continue receiving bills until today and I called the water department they claimed they never received payment while title company claimed they paid those bills. They refuse to answer my calls, emails etc. I need help returning my money or paid those bills.
