Black listed for acounts i did not open

2014 I was contacted by HTN attorneys telling me I owe Sterns and or Foschini account, I told them I don't know the account, I was asked to send a affidavit which I did send and they confirmed receipt. in 2015 I was contacted by MBD for the same accounts wanted me to make arrangements to pay back the money, I explained that affidavit was sent to HTN previous year. I was asked to send the same affidavit and another latest affidavit sent in July 2015 I kept on following up and I was told they investigating, in Aug I advised by the bank that I was blacklisted for a Sterns R9000 from April 2015. again I e-mailed Nkosinathi persistently he rep**** they are investigating no time lines given as they are still waiting for a contract from the Supplier (Sterns)<br> I don't understand why would they black list me whilst investigating. ii also went to Sterns in Trade route i was asked to fill in a form and submit affidavit and id copy which i did and no reference number was given. they said the process will take 90 days. I emailed Sterns from the Website no one has contacted me. My wholelife is upside down, I'm depressed. I need a bond, it cant be granted due to this issue, which I was never part
