Vodacom is very bad

Hello Peter, I have tried contacting vodacom since May 2021 regarding canceling my contract with them which expired on 06/07/2021. Vodacom convinced me to rather downgrade to data only contract which I agreed to and was supposed to be efctive 1/6/2021 but didn't happen because they supposedly say the sim card sent to me was not yet delivered. Let alone, I didn't request this card because I'm using the same card I have.

When I complained Vodacom promised to rectify the problem in July 2021 and give me credit of the difference between what I'm curently paying and what I was supposed to pay under new upgrade and also to give me a complementary data free, which didn't happen.

I'm the 1st July 2021,the new upgrade still didn't happen, and I contacted Vodacom and they said it's technical issue they're attending to it. And still I paid my old subscription and no credit was given to me for the 2nd month and they promised again that come the 1st August 2021,my upgrade will be effected (I have proof of this confirmation). On the 1st August 2021, this didn't happen and when I called them, they still cited the temchical issue that prevented me from receiving the data on the 1st August and gain this time Vodacom promised to pass on the credit of the difference and refund me. Also this time Vodacom asked me to continue using my current plan and said I won't pay more even if I use more they will credit me to ensure that I don't pay more but on the 11/08/2021, I stil rveieved a statement for August 2021,with no credit and again I called Vodacom to complain about this treatment which is not taking away my happiness with their service. The consultant told me that my issue is being attended to online and I should contact online department on ***4, whihc I did but could not get through. Each time I contact them online, via Twitter, they keep telling me theyre attending to my query and will revert back to me with answer as soon as it becomes available (I've proof of this since July 2021) but it gets to monthend and nothing comes out of it and no credits have being received by me for the past 3 months to date.

It seems like now, vodacom is playing games with my subscription because I'm downgrading to blower cost plan to me after they convinced me to stay.

My problem now is that, when I get to them tomorrow, to cancel my contract for good, they might ask for notice period, which I didn't have anymore because I'm fed up.
