How long were you overdue? Did you get a warning message that you would get disconnected? Are you sure that you were disconnected if not? If so you will need to contact Koodo directly in order to get it reinstated. There's a 35 dollar reconnection fee. Maybe it can get waived or reduced if you show confirmation of paying before disconnecting. It no guarantees.
Thanks I was a month behind but no I didn't get any warning. There is no SIM this morning and it still says I owe so it is the bank takes 3-5 days but they should have a system where you can report a payment so they don't suspend your service.
