*********ly *****ing and ruining your credit scorw

I am being harassed by them for 5 years now that I owe them money. It started with an ******* debit order in 2015 I think, that I reversed now am being harassed by credit Intel that I owe them over R1900 and they are putting a trace on me. I never dealt with this company and never have. I am so tired of this.
