Ocwen Misplaced documents Dunwoody Nationwide

 My loan was sold to Ocwen in 2013 yet they show on my credit report that I was late making payments to them in previous years. I refinanced my home in 2012 with GMAC with a 3.25 fixed APR prior to Ocwen taking over the account but the company claims that they never received the refinance package from GMAC. I have been charged excess late fee from the company time and time again. I also receive letters from the company about my mortgage payment that is incorrect. When I call to discuss the issue with the company they always tell me to disregard the information listed in the letter. I have not had a respectful or professional conversation with this firm since they have taken over my account. I'm looking to either sale my property or refinance with a different agency to get away from this organization. I will never do business with them again.
