My number is listed on the National Do Not Call Registry. However, I have received XXXX calls from XXXX since XXXX/XXXX/15. They call up to XXXX times a day between XXXX and XXXX This number has several complaints on XXXX. It is identified as a debt collector from Midland Credit Management. This company left a message on my answering machine for a debt pertaining to a person named XXXX. I do not know who that person is, nor how this company got my telephone number, since I have not done business with them or owe them anything. The calls are a nuisance/harrassing. Thank you in advance for your assistance.
