Approximately 2 months ago our family members and in-laws began receiving telephone calls from a man identifying himself as XXXX XXXX on their personal and private, never publicly published numbers. This included business telephone numbers of cell phones for inter-company use. The man would ask for a family member by first name as if he were an old friend, he refused to provide his true name and company he worked for. He was extremely rude and hung up on family members who continued to ask for this information. He also threatened to have his telephone number blocked if we continued to call him and ask for this general information because he " did n't have business with us. '' After our own investigation, we discovered this man works for CU Recovery, a debt collector in Minnesota. Our family member also recently received a forwarded letter from CU Recovery stating they were attempting to collect over {$8000.00} worth of debt from an auto loan that is over 15 years old, no longer collectible or owed by all applicable state and federal laws, and the vehicle was repossessed and resold at auction from this family member over 15 years ago.
