I have sent payments on my loan modification with SLS loan # XXXX. I have gotten behind a month several times but I have always caught up right away. Several times they have taken a payment made in a timely fashion and credited it to principal reduction instead on to the payment. I have had some success in getting them to fix the problem but with the XXXX XXXX payment due on XX/XX/XXXX they received XX/XX/XXXX they credited to principal and said they would properly credit it but did not do that. I made the XXXX XXXX and XXXX XXXX on XXXX XXXX and once again asked them to properly apply the XXXX payment and they still did not do that. Then on XXXX/XXXX/XXXX I called to make the XX/XX/XXXX payment and found out that they had not fixed the XXXX XXXX payment and I reviewed it with them again and asked for it to be properly credited. They once again said they would correct the problem and took the XXXX XXXX payment. When I called to make the XX/XX/XXXX payment they would not take it stating that my account was in default and sent me a notice of default. I was pretty paralyzed but by XXXX tried to get it fixed by phone again and thought I had finally succeeded when I spoke with a fellow who said he would correct the problem and took the XX/XX/XXXX and XX/XX/XXXX payments. Then in XXXX I get a statement that says my interest is 5.25 % when my note clearly says the payment is 4 %. I make the payments by phone because every time I send XXXX it gets credited to principal and not to the payments and I do not understand why. I have the names and most of the dates I talked to everyone if needed. I faxes them a " qualified written dispute '' regarding the payments, which is what I was told to do, on XXXX/XXXX/XXXX which they say they did not receive, so I sent it again on XXXX/XXXX/XXXX which they also said they did not receive, so I sent it again on XXXX/XXXX/XXXX by certified mail. I finally got a letter stating they received the fax on XXXX/XXXX/XXXX. Then when I found out they had the interest rate wrong I send another " qualified written dispute '' on XXXX/XXXX/XXXX. They say they have not received that one either when I called on XX/XX/XXXX or today on XXXX/XXXX/XXXX. I need to make the XX/XX/XXXX payment and they will not take it. I have transaction receipts for the faxes, a return receipt for the mail and names and dates for most of the calls I have made to them. Please help me.
