Computech credit ******** people

Lately I’ve been harassed buthe computech credit company, send me SMS’s and emails with different emails with different amounts and now they are treating to hand me over to ITC, over a loan amount that I don’t know…I have never taken any loan amount from them nor app**** for any loan from them, when goggling their offices goggle says permanently closed, and when I call their number no one picks up, one of their lawyers called me and didn’t wanna give me her name but told me to do an affidavit from the police station stating that I never took any loan, or made any agreement with them, that I don’t owe them any money and email it to ***, I did that but am still being harassed with emails that am owing them and demanding that I made I make the payment..I don’t know where they got my details, because I never received any loan from them yet they say I owe them
