Horrible service from customer care Multichoice DSTV

Very poor service I received, I paid my account on 20/01/2020 and unfortunately I used the incorrect account number, sent the proof of payment they received it and activated my services. This morning I wake up it is closed again I call the lady I spoke to is not helpful she takes 20min to retrieve my proof of payment and says she is calling the manager and I waited again manager does not call. I ended up paying online again because no one can help me. Now I want my money to be refunded no one knows how to do it, spend my airtime speaking to unhelpful people.
