i know the credit card is good, is koodo overloaded?
Best answer by Dinh
Does Koodo allow payments using another persons credit card other than the koodo phone account holder?
How did you top up? by self-serve or by dialing *611? They had some restrictions for credit card on new account on postpaid if you were using selfserve (I think they might have a similar thing for prepaid but I couldn’t test myself). Those restrictions are removed after several months.
Anyway, if you used selfserve for top up and failed, I would suggest you try the IVR by dialing 611 from your Koodo handset. The IVR has less restriction.
