Misleading sales staff / poor service

I entered into a contract that was supposed to be R99 per month for 1GB Smartdata Top-Up and Postpaid Straight-up 50. My 1st account was in excess of R150, the 2nd was R173.99 and the 3rd is R401.76. How does this work if the account is supposed to be a top up.<br> I have requested the voice recording from the service department who does not seem to be interested in responding to customer complaints. I emailed the service dept. on the 22/01/2016, describing my problem. I did get a response from them on the 24/01/2016 saying they would contact me within 2 working days. I am still waiting for that contact.<br> I then phoned the service dept. today 28/01/2015 only to be told that the person handling my query is not at work. I then requested to speak to the superior / dept. manager, I never did get through to the dept. manager. I waited for than 7 minutes and eventually disconnected the call. I tried calling back thereafter without any success.<br> Is this normal for a big company like Cell C, 1st con and then overcharge the customer and then fail to deliver on customer service. This is the worst service I have ever received and feel that I am being ******.
