No connection after payment made. Line deactivated by SADV

I have been receiving the ****piest customer service from SADV since the beginning of the month to date. I had 2 lines with the network. Line 1 was for 1236 Sihlale street Zondi 1 Soweto. 2nd line was for 1895b Zola 2 Soweto. I made a payment on the 25th of April, using an easy pay number. The payment was meamt for line 2, as it was disconnected and line 1 was still connected and not due for another week or 2. I was then advised that the funds reflected on line 1. When i asked them to move the funds to line 2 they said they cant. Gave me a run around and eventually told me that they have to create a reference number for me to use to make another payment. I asked them to just refund me, they said they don't do refunds. I left it there.

I then made a payment on Saturday 25 May.. Using the same reference number they provided me. And i am being told that the payment is not reflecting because the reference number they provided is inactive. They have sent me from pillar to post yet again. And have sent me 3 different was pay numbers to use next time since in the past 2 days. I am now unable to work aa i work from home and I am not being advised that this will be fixed today. SADV has not customer service number to call. I am losing out on work and im not being assured that this will be resolved.
