Wrong account paid, issue still not resolved.

On 30th November 2019 I mistakenly paid R624 to someone else's DSTV multichoice account using my banking app, I was not aware until December 6th when I switched my TV on. I immediately contacted customer service, they explained that they haven't received a payment from me, I then gave them the numbers that appeared on my transaction history and that's when they picked up that I paid the wrong account. They then said I should send an email with POP attached to their address and that the money will be allocated into my account. The email address they gave me was incorrect. Frustrated as I was after having encountered this,I called again and again and...again! 9 times before midday and still no assistance. 9 good long hours later, I received an email from their side, requesting a VALID proof of payment indicating the date, account etc. The same POPs I sent contained that information!!!! I did as they asked and even sent screenshots this time but still, no assistance. I called for the 10th time yesterday to follow up on the emails I sent, they said their system is slow. Until when? I have sent 6 emails explaining the same issue with POPs attached but my service is still blocked. Instead of them resolving my issue, they keep sending me messages that I must pay my account. I 'm so irritated!!! Dstv doesn't even deserve the 1 star rating, if it was up to me, I wouldn't have given you any star!
