SUSPENDED LINE-***

Hello<br> I would like to lodge a complain against Mtn. On the 19 th Dec 2014 I upgraded my cellphone contract with Mtn. The contract that I signed was a top R369 a month which means that once the 300 data and 100 minutes is finished than I will have to top up. I started using my phone knowing that I am on top up. At the end of January I received a bill of R 488 instead of R369 according to what I signed for and that amount was deducted from my account and I did not make a big deal about because I was told that in the first month there will be extra charges which is for sim swap, etc but at the end of the following month I received an sms that I now owe R 2,700 which is a usage from 21 January to 20 February 2015 ,I phone 808 to enquire about this and that's when I found out that my line is open, I requested for my line to be closed and I requested for a breakdown explaining how they arrived at this amount the consultant told me that my query is going to be sent to technical department for investigation, today my line is suspended but I do make regular monthly payments and worse I cannot get hold of the call centre, I feel like I was mislead by the consultant at the shop.
