I am writing to you about an account that Green Tree Servicing LLC which they purchased from another company called XXXX XXXX XXXX ( XXXX ). My account has been written off by the vendor for over XXXX years or so ago. On my last credit report which it did state it was written off and then the amount on that account was about XXXX times less than what they are claiming. I have all of my credit reports stating that fact. Also, They have been calling my house non-stop. Getting about XXXX of their calls about this. Then non-stop letters in the mail about this as well. I will be sending this information and my concerns to the Federal level, XXXX and also my congress person XXXX about this matter. I already tried talking to one of their representatives about this matter, but all he did was yell at me and also treated me like garbage.
