well he did in a way as blamed their system as are you! No issue if check and double check what submitting. Only people to think it is a bad system are those who made an inputting error which I guess u did as well!
Did u check with provider? Also are you using same sim card/number in phone that is registered to CC? I needed to input OTP to authorise my Hanoi payment
U make it out as if its their fault u entered something so important wrong. Clearly says no refunds so maybe u should have checked all info before submitting?
