Vodacom ripp off with poor customer service

I've been with vodacom for years, never went to any other dealer because I didn't have complaints, But now I have one. This year because of Covid I was contacted by online sales to upgrade my contract. I gladly accepted because the outlets was closed. Got all the detail and spoke to a Jeremy.. Even spoke to a manager as well fo assistance. I've written down all the detail and prices and now the story has changed since I started the upgrade. Now that I have the contract renewed I'm being **********. Customer service can't help me with my router to self check my balance and then the contract is not what was explained or agreed upon. I've contacted online services on 29July and 30 July and the promised a manager would phone back. First day I spoke to a Florence second day to different people and so far on the 1 AUG. still no call back or any type of assistance. How is that for low service and a ripp off by vodacom. I'm disappointed and I feel I want to discontinue this contract because of poor communication and lack of service with a ripp off and the sales person is now in another dept so he can't assist... And I'm still awaiting a callback from the manager
