Don't understand why I can overpay my bill but obviously I can't. Get the message "We are unable to accept an overpayment of more than 20 percent. The maximum payment you can make today is $0.00.". Why not allow me to pay a couple of months in advance?
Some credit cards allow you to have a "cash advance", but usually the ceiling is lower than the actual limit of the card itself. By overpaying high amounts, you could theorically cancel your account with Koodo and ask them to mail you a cheque for your overpayments, effectively circumventing the cash advance ceiling put in place by your credit card issuer.
