HOW DIFFICULT CAN A TRANSFER OF OWNERSHIP BE???????

I did a transfer of ownership from my mother's name to mine in February 2019 at Vodacom Menlyn Mall... The guy assisting us was more concerned with his cellphone and people around him than actually assisting us. The first amount deducted from my account was in March 2019 and on the statement it still had all my mother's info, none of mine. ( So technically it's being deducted from my account but it's not on my name) I asked about it and they assured me that it will reflect on the April 2019 statement... it did not. I phoned Vodacom in April and the lady assured me that they will look into the problem... two ref nrs later (A2-FFDP-YBDU8 and S4-3X52R-RQOE3) no callback from Vodacom ( which I requested ) just a few SMS's stating they will appoint someone to look into the problem and eventually a SMS saying the problem was resolved... It is now June 2019 and the problem is still not resolved. I phoned the call center this afternoon... They don't even know which department to transfer you for help on the issue, they just tell me to go back to Vodacom Menlyn. The issue lies with Vodacom, why did I get 2 reference numbers previously and someone who can help with the issue and now all of a sudden I should go back to Vodacom Menlyn? Unfortunately I still have another year left on this contract, I have a good mind in cancelling this service after my contract expires.
