Failure to refund over payment

On 29th November 2024 as a loyal paying customer of DSTV Multichoice I erroneously overpaid a large some of money on to my account when making my monthly payment. On the same day I reported the matter to a multichoice branch in Edenvale and was advised that the monies would be refunded within five to seven working days. I subsequently had to make frequent enquiries with Multichoice since I had to date not heard anything from them. I am utterly disgusted with the treatment received from the company after making numerous calls on my refund. It is now the 22nd of December and there has still been no contact from them with regards the refund and if you as a customer has to delay any payment for their lousy service provided they would haunt you on a daily basis. I had to make a number of calls and everybody would give you a number of excuses as to when they would refund the money even after them confirming that the refund would be made by the 12th December at the latest
