This can only be a ****

I'm very disappointed with mtn...had a data sim for the past 2 years and it was expiring soon so I went to the store 2 months prior to that and asked them what happenes to the contract if I choose not to cancel it...they answered and told me that it will continue as is until I cancel it so I was ohk with the data I was receiving so decided im gonna leave it as is.and now the the contract ended and 3days later I receive an sms saying my contract has expired and I will no longer be paying R200 but will b paying close to R600 per month and it will b now running on month to month and this is not what I was previously told so I called in to cancel the contract but now I was told I need to pay R1000+ in order for them to be able to cancel my contract.i ask the lady is there a charge for cancelation and she said NO...so what is this money for that you want me to pay and she beats around the bush and keeps explaining something that didn't make sence at all! She ends up transferring me to someone with better understanding and that person tells me i have to pay all outstanding balances befor they can cancel my contract and mind you I have a a cellphone and data contract in my name whitch I pay for month end and now I was told that in that in order for them to cancel my contract I have to pay for the contract that I had already payed for in advance for the next month and again pay this R600+ of the data Sim that they changed without my consent or even notification that I have only used 3 days off...HOW THE HELL DOES THAT EVEN MAKE SENCE? the consultant could not unswerving me.so I decided I'm gonna pay up and never take anything from mtn again but befor that I asked the consultant what will hapen to the data that im now forced to pay for that i have not even used yet after i cancel the contract the they give me the most ridiculous answer ever ! YOUR NUMBER WILL B CANCELLED AND CEASE TO EXIST MEANING I will loose all the benefits that I have already payed for! Now this is what I call a joke and a ****! So I told them I deputes that payment due to the fact that I was given the wrong info or either ****med by MTN to get more money out of me since i was canceling the contract. They gave me a ref. No and told me someone will call me to rectify this but it's been almost 2 weeks now but nothing. I'm so disappointed with mtn and hope that this can go out to all the people who are also about to fall victim of these ****s...now we are being ****med not just by fly by night Companies but also the companies that have been around for decades that we thought we could trust
