I'm a Cogeco customer and so far this month there Meter is out over 5Gb's compared to my DuMeters results. You call in and complain and all they do is open a ticket and say lets wait and see.
Come July when people start getting there bill for June and they see these charges for usage they didn't use..... Well lets just say I wouldn't want to be a Cogeco rep when the shit starts hitting the fan.
Contact the provincial consumer protection office and file a formal complaint.
See whether you can get the local Crown Attorney to file fraud charges.
