Poor Service delivery

On the 24/05/2021 I went to vodacom shop at carnival Mall to open my sim card that was closed by me since my phone was lost. the sales person was so nice he managed to twist me to upgrade I did upgrade I received Huawei Mate Pro 40 and my sim card was re-open , i was told to wait for 3 hrs before I could insert the card to my new device since I did sim swap. on my supprise I picked up that my account was suspended i waited till the morning I then contacted vodacom 135 contact centre i was refered to collection department , then later moved to legal deartment since my account was already been handed to the as per the consultant. I was so shocked about this since I have always paid my account up front and I just recently been told that I was due for the upgrade how can I been handed over to legal just for agreeing to upgrade and take new device. I went threough legal I spoke with very friendly consultant who saw it was mistake from the vodacom side to put me on their deparpament he promised that this issue will be resolved within 48hrs and which 26 days later I am still waiting for my line to be reconnected or open. on my supprise today vodacom is going ahead to invoice me for something that I havent even used it. this is really frastrating me big time as I use my phone to excecute my work. I have called in today to try to reverse or cancel the contract without unticipating any charges against me since I never failed vodacom even the past contract I had with them , it is them that has costed me big time by suspending my line.
