I have been making my mortgage payments each and every month on time, and have even put in an extra {$100.00} each month towards the principle. I started making my payments in XXXX of 2014. I found errors on their invoices about the due dates that was two months ahead. I let the lender know that this error was on their invoices. About six months ago, the lender sent me a letter stating that I had missed a payment, but after going through with their dispute department, they realized that were wrong and that I had made all of my payments on time which they said they had corrected. But after looking at my future invoices I realized that my principle balance had n't gone down between my payments. The lender has gone back and un-applied some payments and reapplied them back again, but are wrong in their calculations and have caused me to be short on my escrow which has raised my monthly by almost a hundred dollars a month. We are in dispute right now and my original lender has been trying to work on my behalf to correct these errors to no avail, even though my original lender sees the errors, but has been unable to explain to me why this is so. I have just received another letter from this lender saying that they were transferring my loan to another company, I believe this company knows that they are at fault for these errors but some reason, they are unwilling to correct them and passed the loan off the someone else.
