Cell C Contract

I took out a Cell C contract in December 2014 for a Blackberry Z contract of about R185 (not sure if the amount is correct, but not more than R200) per month. <br> <br> In January 2015 Cell C deducted R387.81 from my account and then in February 2015 another R271!!!!! HOW IN THE HELL???? I then contacted Cell C's customer care number (084 140) and spoke to an agent who informed me that Cell's prices have gone up and that I should have received an sms about it... now first of all I am not even three months into my contract and the price has already gone up... Why has the price gone up if the price stipulated in my contract is what I am suppose to be paying... I feel like I am being cheated by Cell C and am really ****ed off.... <br> <br> I now regret taking out a contract with Cell C, cause not only have I had endless problems with the network in my area, now they are messing with my money!<br>
