Your local TV stations and/or newspaper may have someone dedicated to helping people like you. Exposure in the local media tends to bring quick results.
Also we once had a problem with Bank America, they took over the local bank that my minor kids had accounts in. Once they had control they basically looted the accounts with service charges. I had the the kids make signs saying "Bank America stole our money" and had them picket the bank. Within 30 minutes the manager was out there and first threatened the kids with arrest, I laughed that off and pointed out that the sidewalk was public property. She then quickly gave in and paid them their money. Some picketing on Saturday which is probably their busiest day might produce results.
