Norman Bisset

I received a call from Norman Bisset claiming they act as Nimble Group and I need to pay an MTN account which was closed years ago. The agent told me outright they bought the account from MTN. The account was closed because of an error they made on my account which they refused to correct. The attorneys to whom the account was handed over, refused to proceed with the account when they realised MTN was at fault. According to my understanding of the law Norman Bisset is not allowed to buy the account from MTN or collect any so called outstanding debt after a certain number of years. When I pointed it out to them, they promised no money will be deducted from my account. During the phone call they created static interference on the phone line in order to create the impression that they cannot hear me pointing this fact out to them. I have phoned my bank and asked them if it is possible to block any transactions from Norman Bisset. Should they dare to proceed with their ******* activity I will hand over the matter to the Ombudsman and to attorneys for attention.
