Residential Credit Solutions PLEASE help Im not late on my payments but i get harassing calls all day this is a scam Fort Worth Texas

 My loan was sold from GMAC to Ocwen. Ocwen then sold to Residential Credit Solutions. I have had nothing but problems from this fly by night opperation. Im current on my Mortgage but every month I get haressing calls that my mortgage is late. Calls will start at 8am and continue through out the day. I tell them its been paid. I send to a post office box. I believe they pick up payments after the 15th and charge late fees. I called and asked for them to remove the first late fee they said they could not. I paid the first one because I dont want my credit marred.

After researching this scam I stopped paying the so called late fees. I now will have to send my paymeny by certified mail and keep all records of when my payments was sent. I work for a Title Company and this can be a mess when I want to sell. My pay-off isnt going to be correct. I do-not have the funds to hire an Attorney. We need to stop this scam and close this down. Anyone who can help I would greatly appreciate it. I feel we have a good case against RCS. They are also messing with my escrow account. Did -not  pay a tax that was due so I will have to pay. HELP !!!!!
