Contract termination horror

Beginning of October I changed ownership of a line that belonged to my employer (previous) to my name and also requested that it be changed to prepaid. In November I noticed that I couldn't load airtime or view balances and I initially thought it will be something temporary but when it wasn't changing I called Vodacom citing this and I was assured that it is changed to prepaid. On the 14th I remembered that I did not record details of the persons I was dealing with previously so I called again and was assured that the number is on prepaid so I asked for the agent's name to record this. 20th Nov the App reflects that I owe Vodacom R6159. 29 so I call Vodacom and get the same response and send an email to *** and never received any response except for the automated confirmation of receipt. This went on till Dec and agents started dropping my calls as soon as I give them my ID number, which is still the case to this day. I owe Vodacom 10k and they have now deducted it from my previous employer, so I basically owe my previous employer now.

Ohh in October they deducted R288. 09 for a number I don't know and I had to submit affidavit for them to ctedit me that money. That credit was used to reduce the mysterious bill. After posting the matter on social media I was called and the bill was now 11k, the person I spoke to promised to get back to me last week on Thursday. I have been sending reminders since but haven't received the call.
