Breach of contract - Vodacom

I wrote a quick review last week in an attempt to solve my issue with Vodacom - after a few promises by them, my issue remains unsolved and no more communication from them. So here is the full story:

In July 2023 I downgraded two of my contracts. In Oct 2023 Vodacom Online contacted me and offered me an upgrade for the same two contracts and this was due to my existing contracts no longer existing (According to Vodacom Online).

The upgrade would even cost me less than the existing contracts (roughly R 20 / month less for each of the contracts). Furthermore, the gave me two handsets free of charge with no monthly cost. Again - all of this offered to me for free by Vodacom Online).

Unbelievable? Well, you better believe it. It is even recorded as such on the call recording and I made double sure that I do not increase any of my costs.

Well, end October I receive my monthly statement form Vodacom and my monthly fees doubled.

When I enquired about this - Vodacom didn't respond. When I posted the review on this website Vodacom quickly rep**** on this chat and contacted me but still the issue is not resolved.

Vodacom went into a new contract with me on 6 Oct 2023 and are now breaching that same contract.
