Lying and cheating clients

I have taken a smart tab with Elite Mobile in less than 2weeks ago but I am already fed up with them already. I have told the sales lady that I am not interested in any of other additional services except the smart tab offer of R 89 per month. The next thing yesterday I get messages that says welcome to hotspotter and some rescue box and then I get login details as well. I called the 0861 number that they say its queries and speak to the consultant and she said to me I subscribed to this services the day I took the smart tab offer, I said no I did not take those things. She assured me that she cancelled those and I will get an sms to say she cancelled them for me. Today instead of getting cancellation sms I get congratulation sms that says my order has been approved. What on earth is really happening, just touch my account debiting for those extras that I did not ask for, I will take this further and I will make sure that person responsible pay for what happened. I have all the names in place. I regret the day I took this contract already. I wish I can go to other mobile networks I never had such problems.
