Webafrica still did not reverse my money (ID: ***)

I have been using Telkom LTE through Webafrica and ever since I signed up I always paid my account manually as arranged as the card facility did not want to except my card for some reason and ever since I had no issues until this month. Last week Saturday(01/02/2020) I paid my account manually R459 as it was due but then on Sunday(02/02/2020) they debited my account and took R459 again. I contacted them and asked them to reverse my money as I already made payment on Saturday and I was told my money would be reversed on Wednesday(05/02/2020). come Wednesday they tell me I have to wait until Friday for my money to be reversed. it is now Friday and I still have not received my money and it is money I needed to use to pay another bill and due to Webafrica I am now late on my payment and still don't have my money. I have been contacting them the whole week they just have excuses the whole time. this is really unacceptable for me to wait so long for them to reverse my money when they already have proof that I made payment. I have always paid on time and it is surprising that I get treated like this and now I have to explain why I am late on my other payment.
