Don't even attempt a cancellation - nobody helps

I took out an upgrade for my daughter on the 24th June 2025 but shortly after this she found out she was immigrating so we called the Vodacom cancellations department (*** at 09:50 on 2 July) 8 days later (within the 14 days cancellation period) to cancel the upgrade. They advised I need to go into a store, so I went to the store that afternoon and the store advised that the upgrade was done over the phone which goes through a call centre so they cannot proceed with the cancellation and I need to do it directly with the call centre. I called the call centre *** at 15:55) the following day (9 days post upgrade) and they said they would come back to me the following day. After continuous follow ups, eventually 7 days later the call centre calls back to say I am out of the 14 day period, I confirm that I contacted the store 7 days ago and they said they will come back to me. They never came back to me, to this day. I escalated this to X and have been contacted by Vodacom but they keep telling me I did not contact them within the 14 days. All the calls are recorded and I have my call log of all my calls yet they “cant find” the recordings. I just want this contract cancelled! I have been a Vodacom customer since my first cellphone many many years ago and I have been loyal to them, every upgrade is with Vodacom but I think it is time to move to MTN but from what has been happening with this one case I do not think I would ever be able to move over to MTN or CELL C because Vodacom call centre DO NOT KNOW WHAT THEY ARE DOING, they are not informed, they are not trained properly and they ignore all queries. Calls are recorded so please go back to the call log and date I sent on Twitter and listen to that call then cancel this contract IMMEDIATELY!!!! I have wasted hours and airtime phoning people who do not know their job.
