Hello! I bought last Wednesday a koodo-phone with prepaid card. I wanted to activate my account, but when I'm on the payment page and I type in my PIN number valued 20$ (I just have to pay 5.75$ for my add-ons) it's said: "valid top-up vouchers with enough service credits to cover the total amount owning are required." But I do have a voucher for 20$, so why doesn't it work? Please help me! I just have a German credit card and not a Canadian one, so I have to use the vouchers.
