Bad service by Vodacom and their employees

On 29 September 2022 I was contacted by Vodacom upgrade Department in that I was due for an upgrade. Mandiza explained to me what the upgrade was about and that the call is being recorded. I agreed to a R279 contract (SIM ONLY + 20GB X 1 (H) + 1GB VID TKT X 3 @ R279 Reduced Sub PM on Red 1GB 200min TopUp. On 1 October 2022, I received a quote from Vodacom for a 24-month contract at R929 per month. I DID NOT AGREE upon. I phoned the upgrade Department to rectify it and the lady (I cannot recall her name) I explained the situation and she said she will have to speak to her manager to rectify my contract and phone me back. Once again CALL IS RECORDED. She did phone me back and confirmed my contract as rectified and as agreed upon as SIM ONLY + 20GB X 1 (H) + 1GB VID TKT X 3 @ R279 Reduced Sub PM on Red 1GB 200min TopUp .... R279 x 24 months. Today I phoned Vodacom again as the Vodacom app showed my balance due at the end of October 2022 as R 929. Once again, I phoned Vodacom upgrades and was by the lady I need to speak to customer care about my problem, she then transferred me to customer care, Lilly tells me the call is recorded and she will escalate my request. My 3rd ref no ***. Vodacom employees are committing ***** to their customers by adding services which was not asked for....., they tell customers the call is recorded and when you ask a copy of the recording, they reply they will send it and that NEVER happens. Vodacom needs to properly train their employees and not lie to customers or commit *****. I am fed up with phoning Vodacom urge Vodacom to solve this problem immediately!!!!!!! I have been I client for over 25 years and this is enough now. I would like to cancel all my contract with Vodacom
