Multichoice - sub standard/poor services

I cancelled my DSTV account November 2019 so that i could stop the very poor services given by the staff of Multichoice. To date instead of my account being cancelled, to my astonishment I now have 4 active Decoder accounts to my name. This has negatively impacted my credit score. I have been given the run about by the cancellation department with the most popular phrase "I will escalate the the problem". I am told that the cancellation department has a high call volume which is an indication of the number of people wanting to cancel their subscriptions. Please think twice before subscribing to DSTV. Poor or no service is all you must expect. I published a review last year (Nov) about the sub standard service that Multichoice has given. The review received a quick reply from a "manager" who wanted to know how this could be resolved. He then went on to promise that my problem would be resolved. Being unsuccessful I then published another review which then got me another response of promises which to this day has not been met. Now I have published this review and challenge the company to resolve the issue.
