The problems with this mortgage began years ago. To get an understanding of the situation, I must give some background information At the end of XX/XX/XXXX, the XXXX I had worked in for 15 years closed. I had difficulty finding a good paying job. My wifes business partner decided he wanted out. We lost our investment. Our income was greatly reduced. Select Portfolio Servicing was the servicer of our mortgage. We applied for a mortgage modification. Select portfolio advised that was possible provided we meet certain stipulations. We did what we were supposed, but the mortgage was not modified. This was repeated two times. In XX/XX/XXXX we were again told if we made 3 payments the loan would be modified. We made the payments. The loan was modified effective XX/XX/XXXX. But before it was completed, Servicing was transferred to XXXX XXXX. The first statement we received from XXXX showed an amount more than the modification stated. We were both unemployed. We had no choise but accept their word. Effective XX/XX/XXXX servicing was transferred to XXXX XXXX. Again a diccrepancy in balances. The monthly payment increased from {$1400.00} to {$3000.00} then to {$3500.00} then to {$1900.00} in 4 months. We made calls and wrote letters. Nothing happened till XX/XX/XXXX we received a letter the payment was {$1400.00}. We continued disputing the balances. In a letter dated XX/XX/XXXX was a history of our account. We questioned many entries. We received a letter from the President of XXXX that the balances transferred to them were wrong. He sent a Simplified Transaction History ( STH ) for us to use in determing the balance. In a letter dated XX/XX/XXXX he assured us that the STH gave an accurate balance as of XX/XX/XXXX. We used this to develop our own records. Effective XX/XX/XXXX servicing was transferred to XXXX XXXX XXXX ( XXXX ). XXXX added a new item which was not on the prior servicers statement. Each month we wrote QWRs disputing the balances. This went on through several servicers. We wrote QWRs. The servicers would send letters filled with irrelevant statements, but would not address the issues. Several times we wrote complaints to CFPB about it. On XX/XX/XXXX we wrote complaint XXXX against XXXX XXXX XXXX ( XXXX ). In a letter to CFPB dated XX/XX/XXXX XXXX stated they would do a complete analysis and get back to us. We are still waiting. Servicing was transferred to Select Portfolio Servicing ( SPS ) effective XX/XX/XXXX. On XX/XX/XXXX we wrote a QWR disputing the balances on SPS statement dated XX/XX/XXXX. We submitted copies of applicable documents on which we based our records. We submitted copies of the spreadsheets on which we calculated the blances. SPS responded to our QWR in a letter dated XX/XX/XXXX. The said the issues were Service Transfer, Validation of Debt, Origination, Payment History, Corporate Advance, Payoff Statement and Fraud. It was these items they discussed. The did not respond to our issues or the documents we submitted. We have written QWRs each month disputing the balances. SPS has not addressed the issues raised in out QWRs. SPS refuses to address our issues. SPS fills their letters with untrue and irrelevant information. Under separate cover we are mailing copies of all applicable documents which support our charges. They include our QWRs to SPS, the documentation supporting our position, SPS responses to our communications. Our QWRs and other letters clearly show how our records have been developed. They provide documentation to support our position. SPS responses show that they do not address the issues we raised. SPS responses contain many untrue statements. SPS responses do not provide any credible support for their position.
