The J. C. Christensen & Associates , Inc. collections agency located at XXXX XXXX XXXX XXXX XXXX, MN XXXX has been sending a large number of letters to our address. The letters are addressed to XXXX XXXX XXXX who does NOT live at this address. XXXX XXXX XXXX is a neighbor who live across the street from us and just happens to have the same last name. We do NOT owe any debts to this agency, or any agency for that matter. It is an inconvenience to have to walk over to our neighbor 's house and hand over their letters every time we receive them. Finally, my wife took the measure of returning XXXX of these letters to the XXXX XXXX with a request to stop sending them, but the request has been ignored. I presume the agency thinks we are deadbeats requesting a stop to collections activities when in fact we are NOT the rightful owners of this debt. Failure to cease communication upon written request is a violation of FDCPA. We request this agency cease and desist from sending letters to our address. I also have UDAAP concerns about the letters. The letters do not name the creditor and just say " Time Sensitive Document ''. The most recent letters are yellow envelopes inside of a white envelope with a clear panel on the outside envelope, which seems pretty shady. I never open these letters, since it is a crime to open someone else 's mail, but finally did a XXXX search on the return address to identify the creditor. We sincerely hope the CFPB can bring a stop to these harassing letters and change the business practices of this agency for good.
