How bad and selfish can this firm get? My Aund and Uncle had a case with them, but we transferred to a new firm because the lawyer that was responsible for our case transferred to the new firm, and Hyder and Overas will refusing to transfer our funds to the new firm. Hyder and Overas did nothing for us and still wants to keep our money. VERY SHADY BUSINESS.
