I don’t believe so. You might not even have access to self-serve. I’d say call #227 from your Koodo phone but that may not work. You could try requesting a callback from koodo.com/chat to get assistance on how to pay.

my phone is shut off so a call back wouldnt work

Let me flag a rep for you 

Hello! If your account has been assigned to a collection agency, then the payment can only be made with them. To find out their contact info, you can get in touch with our colleagues over the phone by scheduling a callback at koodomobile.com/chat (if there is another number you can be reached at) or by going in a store (see here koodomobile.com/find-nearest-store for the nearest one to your location). Please keep us posted if you need more help.

Did you receive a letter from the collection agency? If so, you should be contacting them directly and ask them what methods of payment are available to pay off your debt. In many cases, you can pay it in the form of a cheque, online, or even at one of the bank branches if they allow this.
