Multichoice-Payment Reversal

I have been paying our dstv via eft on the same date for the past months with no problem. On the 28th December 2019 I did the same and on Monday 06th January 2020 our service was suspended, I called dstv and they reconnected our service and apologized for the error on their part.On Friday the 10th January 2020 our service was suspended again and this time I was told its because I reversed the payment on the 06th January 2020,which I did not.I was asked to furnish them with proof of payment which was my bank statement and I did. On Sunday the 12th @11h39 I received an e-mail from their Billing Escallations saying that the statement I send them does not show that I did not do the reversal,i responded that it is fine I will go to the bank and get a stamped one proving that I did not reverse the payment which I did and I emailed it to them (Ref no: ***)back. To my horror on Wednesday the 15th January 2020 when I got home during lunch the service was once more suspended due to "I reversed the amount" I called them and their call center agent had an attitude from hell,but we managed to work together and she arranged that the service be opened for the next 5 days while they are still trying to locate as to where that amount went to (Ref no: ***). Now it is very disappointing to hear that I'm not the only one with this problem of reversal on the 06th January 2020. Multichoice has really appauling service.
