NO STANDARD BANK ACCOUNT - but being harassed by debt collectors

For the last 5 or more years I have been receiving threatening calls and harassing calls from their offices and their debt collectors. I have tried unsuccessfully attempted to get my number of the the Standard Bank Database. I am not an account holder at Standard Bank, neither have I been since the mid-1990's. The last time I complained on HelloPeter I was assured that this would be remedied and for a short while I have had a reprieve. I have just a call and when asking to speak to a supervisor the call agent put the phone down on me. SB if you don't stop I am going to open a case of harassment against you and your agents. I have had this number for 15 years. Surely by now you have tracked this woman down. Please call me urgently to remedy once and for ALL. I have just had it in chunks. No time to be polite anymore.
