***** on my Name!

For 6 years I am being hounded by debt collectors about an MTN account that I do not have, and never had! I had to do 2 affidavits with my signature 6x on the page to prove that it was not me. Then it's radio silence for a year, I think it's resolved and a new debt collector phones me. I block numbers and explain to them that I am not going to go through this again. Yesterday Nimble requested that I pay a settlement balance to clear the matter and I refused because I do not owe them any money. Please can this stop! It has been 6 years
