pathetic service and false sales information

I was offered an additional cell contract with data, in the sales call I asked if I need to rica the sim once I receive it and was told, all I need to do is give my ID and proof of address to the courier and all will be sorted. I received my sim card and had it activated, in that call I one again asked if I need to have the sim rica's and again was told no. since then I have been calling on a daily basis only to be told that there is a rica block and I need to go into a mtn store which I refuse to. I was told that I didn't have to in the sales call. I then called your cancellation department to cancel that contract and then get told I need to call sales to cancel it. lost time I checked, when you call cancellations they are the ones that are supposed to help? pathetic service and false promises from all your departments. I want this contract cancelled and I refuse to call different departments for you to sort this out.
