Lack of Communication

I have been paying Nedbank Credit Card since December 2016 under an arrangement. In March 2017 Jay Mothibi Attorneys issued a Summons against me which was then sorted as I called the Attorneys who said they would contact Nedbank to confirm the arrangement. I then received a Warrant of Execution against my furniture by the Sheriff of the Court on a Saturday 18th November 2017 with the Attorneys name on the Warrant. I phoned Jay Mothibi on Monday 20th November 2017 and they say they would not issue a Warrant as I have an arrangement with Nedbank Legal Department on which I have never defaulted and yet I had the Warrant in front of me. Why was this loop between Mothibi and the Sheriff of the Court never dealt with. It is despicable that there has been such a delay in communication.
