Exorbitant bill

I have a 3G contract on MTN with Autopage Cellular but it was NEVER explained to me that it was not a top-up contract, or what the exorbitant out of bundle rates are. My contract is R125 pm and has been fine for the past few months, until Nov 2015. I was then hit with a bill of approximately R17 000!!! All the people at Autopage told me is that is was my laptop doing back-ups. Yes, so that may be true but I was NEVER warned about these excessive costs. I think this is totally unacceptable. I am now almost bankrupt and am considering approaching the Consumer Protection Board for help with this matter. <br> <br> Please help!
