Vodacom online deals - beware

I did an online upgrade on 20 June 2024. I received my phone and accessories and was very happy with everything. On the 15 July 2024 I received my invoice and noticed that there is an additional number for a Red VIP 22g contract. I contacted the call centre just to be moved from one department to another and always telling me they will call back and give me feedback. That did not happen. I have called vodacom so many times and they still did not resolve my query. They added a new contract to my account instead of upgrading my current no that is due for an upgrade. I am so gatfol for vodacom not taking responsibility for anything they do. But will start cancelling my 5 contract numbers with them as soon as the contract expires. Starting with the 3 That are due for upgrades. What a ¥*^%#} joke that no 1 person can give me a direct answer on how this happened.
