Data contract upgrade gone wrong

I called the contact centre in September 2023 wanting to upgrade to a better data deal. I was given a better deal however I was never informed that the contract is now going to be for home internet only, meaning I will no longer be able to use the sim card on a cell phone. I only noticed this when I could no longer hotspot myself or connect to the internet on my cell phone. I called Vodacom informing them this problem, this is when I was informed of the type of data deal I upgraded to. I immediately asked them to cancel the upgrade and put me back on the old/previous contract I had. I was then informed that the contract has been cancelled. In end of October 2023 I went in-store to check if I can get another contract deal since the previous upgrade was not successful. To my surprise, the consultant tells me that the upgrade was cancelled and I was placed on another contract which I will be paying more than I initially did with my old contract😡So they not only cancelled that upgrade I asked to be cancelled but they upgraded me on another contract. I am frustrated to say the least….Today 19/11/2023 I went In-store (Menlyn mall) to sort this problem, only to be informed that they cannot solve the problem they can only escalate/send a request for the online “store” to solve the problem. From paying R320 to a bill that is R550 or so😤 I will not pay for peoples mistakes….It is not my fault that they made a mistake. Vodacom must sort this out ASAP - 7 days is just too long for them to get back to me!!! As a result I am stuck, can’t even enjoy black Friday deals because of this. I am so disappointed
