My mortgarge was sold from XXXX XXXX XXXX XXXX XXXX immediately to Cornerstone Lending. My first issues began when I paid my shortage amount in XXXX 2015. I paid in plenty of time for it to be applied to my account. My bank statement showed Cornerstone cashed my check on XXXX XXXX. I called to make sure the payment had been applied, I was told it had not been as of XX/XX/XXXX. I had to call back in a few days to make sure, which I did. I was told a few days later that the amount was applied and my new payment would be XXXX. They did not credit my account which resulted in the wrong amount being withdrawn in XXXX. My bank statement showed XXXX being deducted. I called again and was told they would apply the extra amount, over XXXX to my principal per my request and that my XXXX payment would be XXXX. I then, XXXX., received a letter stating they had not received my payment of XXXX and my XX/XX/XXXX payment was late. I called and spoke to XXXX who said, no, that was incorrect, my payment had been received ; I have autodraft, and to disregard the notice. I got another letter dated XXXX or XXXX that said " thank you for your XXXX payment ''. Last week, XXXX XXXX about, I began getting phone calls with no one on the other end, from New Jersey. I ignored them. I got another one today, it connected, asking me to call Cornerstone. I called and was told my XXXX payment had not been recieved. I had to call my bank so they could send a letter verifying the payment had been made. Again, I have autodraft. I asked to talk to a supervisor. I spoke to XXXX who said my XXXX payment had been applied to my principal, so no payment was made in XXXX. 
I am losing my patience with this company! I got another letter today stating they had assessed a late fee and my payment for XXXX is {$1500.00}! I can not take this anymore. 
Please help.
