harassed consumer

These people call me on a daily basis regarding my previous TGF group account that I settled on 01/08/2017, and I was given a settlement letter. So they harass me and tell me I think I'm clever running away from my credits, whereas I told them I owe no one. and now they even call my Dad threatening him.

My credit score is higher and when i check, Transunion, clear score and Experian the account doesnt appear anyway. This MBD is a ****. No person must fall for their trap
