Complaint

I have a contract at vodacom. Friday 8 September I was told they will send a vodacom kicka 6 because I was a loyal customer to them. They did tell me it will be free so it won't affect my current contract and I did ask them if it would a problem if I want to cancel my contract October because November 2023 my contract will end and the guy said it won't affect my current contract and I can still cancel it. This morning 13 September I've received and sms that state that they have successfully upgraded my contract which was not confirmed by me. I want vodacom to fix this mess because I don't want to upgrade my contract their services is so bad. I'm really fed up with vodacom.
