Vodacom horrible service

Second time I am writing a review on Vodacom for this matter as it seems it is the only way I can actually get them to contact me.

Vodacom offered me a deal on my contract (which was ending) which I accepted resulting in a cheaper package which was supposed to start in October 2022. My account from then until April was still debited the full amount and after numerous complaints and phone calls I was only refunded for 3 months of over charging and made to feel as if I should be grateful even though I was not refunded for the rest of the time I was overcharged.

After many back and forth calls they promise to have someone call and sort it out which generally does not happen. When I do eventually get a call back they promise to sort it out only to hang up and seemingly disappear because I can never get into contact with them again.

The latest is I have been charged even more than the original amount this month with no explanation. I want a refund and then cancel my contract.
