Lender Live Debt Collection Complaint

Lender Live Debt collection department,

Mortgage Cont'd attempts collect debt not owed Debt was paid

Since - - - - ( Under Lender Live - - - - - - -, CO - - ) assumed my mortgage debt from - In - 2015, I have experienced nothing but harassing phone calls and now false reports on my credit report. Each month through multiple harassing calls I have informed and provided documentation that my mortgage has been paid for the month and that the lender has cashed the check. Each month is a different excuse, such as : they misread the account on the check or when I sent it through their web site, I was told it was the wrong account. Now they are sending letters not to my mailing address, but to the house ( which is rental property ). Also, they have began placing late payment information on my credit report. I have documentation of all cancelled checks, verification of payments submitted, and email correspondence where I have identified the issue each month and provided the information for them to correct. I have never been late on a mortgage payment or had any issues until this company assumed the mortgage. I would like this matter corrected and my credit report adjusted immediately. Your assistance is appreciated.
