hey had a bug in their app, which led to 2 voucher purchases with our credit card which we never authorized! We were overseas the day the transactions occurred, never even opened the app, and suddenly our credit card was charged for 2 vouchers from Canadian pizza (2 separate transactions). We contacted customer service who replied we must have "accidentally purchased it". Come on, 1 transaction maybe, but 2 accidents?? Worse still, one of the vouchers was a 1 for 1 pizza at 20.43, which is more expensive than if you were to buy straight from Canadian pizza which is$20. Cheats!!!
