Just registered a prepaid account with Koodo and signed up to automatic top ups. I was surprised not to have an option to choose an amount that would exactly match my monthly renewal fee. For instance, if you have a base plan of $15 and a discount of 10% for registering your credit card, then, your regular top up would be $13.50 plus tax. The only options at the moment, in such a situation are too little or too much, ie, $10 or $15 plus tax. So, my proposal is to match automatic tops up with standard amounts or at least have an option to write in a unique top up amount. Thanks for reading.
