Hello Fozzybear88,
Welcome to the community!
Generally, any credits on your final bill would be sent to the address they have on file. As far as I am aware, a credit balance will be mailed out to you 2 to 3 weeks after your last bill had been generated (see here). However, that does not mean you would receive it in that amount of time. It may take 4 to 6 weeks to receive the balance.
If you have another active account with Fido, they may be able to transfer the credit to that account. However, they would not be able to transfer the credit to an account of which you are not the account holder (see here).
You should note that the forums are community-driven and not intended as a venue for customer services. As such, we would not have access to customers' account information. If you wished to discuss your situation, you would need to contact customer service. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
