Profile damaged by dmc

I’m very disgusted with this bogas company that I don’t know where they got my details, they called me to and send they calling with regards to finchoice debt which I settled and finchoice gave me a settlement letter , now they are spoiling my credit profile as if I’m in arrears, they should remove my name from their data before I go the legal root/ finchoice gave me a paid up letter customer No MaM19953/ contract no ***3 I had no business with dmc never had contract with them
