Vodacom customer service is extremely poor and the knowledge is even more poor

I have taken a 36 months contract with Vodacom. i went to the store 2 months ago and the store to cancel my contract was advised to call up customer service to cancel my contract. my contract ends on 10/10/2025. i called the customer service team today 11/09/2025 to place my 1 month notice to cancel my contract. I spoke to Mr Naidoo he advised he can not cancel the contract i must call up next month to cancel my contract. Please can Vodacom explain why the shop and the call centre is not aligned. The call centre and the shop are lost and do not know what is happening. Can someone advise which is correct process to cancel my contract.
