Kindly refer to this website where other customers have put the same complaint..
Same thing happened with me..I have been Rogers customer for long, and have been moderately using the internet without exceeding the usage limit. Now suddently I have been charged $88/ extra for usage of 44 GB above limit for Aug 09-Sept08 payment period. I called Rogers and talked to customer service and technical service, but as usual they were not able to help and not ready to help and resolve this issue. I then submitted complaint to Rogers online complaint to Rogers president office. They have also turned deaf ear to it, and no one has contacted me as yet. Again the message is popping up on screen You have exceeded 100% limit. When contacted technical support, they are saying it is already 30 GB above limit..Rogers is not fixing their problem on their end, and not helping customers listen to their genuine grievances, and charging customers with heavy internet usage fee. It must be stopped. Read below online complaint of other Rogers users
