Multichoice DSTV bad service

Good Day, we cancelled out DSTV December 2023, we physically went into the Multichoice DSTV offices in Newton Park to do the cancellation, we paid the final R196.00 that was outstanding on our account and asked them to cancel everything DSTV related that was linked to our name. we asked them to disconnect it at the end of the month, well, when we got home that afternoon the service had already been disconnected, but we did not mind. NOW< two weeks ago we got an sms from Multichoice informing us that we have been handed over for outstanding amount of R220.97and if this is not paid they are going to suspend our service. This is now a service that was cancelled nearly a year ago, we have not had DSTV since December 2023. We went to the Multichoice offices yesterday to query this sms that we received just to be told that the outstanding amount of R220.98 was the insurance for our decoder that was not cancelled, and no matter how I tried to explain that we cancelled EVERYTHING Multichoice related the less the person that was assisting us understood, all he said is that if we do not pay it could end up in court. I would like to know apparat from going into a business and cancelling everything linked to your name and ID number, how can one be sure that the person that you are dealing with is actually cancelling EVERYTHING as requested to avoid an sms telling you that you have been handed over for an outstanding amount for something you no longer have. We really do live in a country where you actually need steelwool and nerves of steel to be able to deal with the incompetence of the people that get employed to assist you as a customer. Thank you Erica-Ann Please note that the account for DSTV was on my fiance name and not mine. Mr MA Kieth
