Hello Svkshailendra,
Welcome to the community!
Sorry to hear of your situation. However, you should note that these forums are community-driven and not intended as a venue for customer services. We may not be aware of all Fido policies and any changes to those policies.
Unfortunately, Fido would not be able to directly deposit the final bill credit amount to a bank account. That's why they require the issuance of a cheque. Those cheques would be sent to the billing address on the account (see here).
That said, as far as I am aware, it may be possible (at least it was) to send the cheque to an International address (see here and here). I believe you would need to update your billing address on your account. However, I'm not sure if their policy on the matter has changed since those posts.
I understand you have already spoken with them, however, if you would like to update your billing address, you would need to contact customer service. Unfortunately, they appear to have removed their customer service via social media options. In addition, they also do not provide customer service via email since that mode of communication is inherently insecure. I understand you are currently outside of Canada. They do provide a number to call From Abroad. Calling that number from overseas would not incur roaming charges when called from your Fido SIM (see here). Alternatively, customers should also be able to call that number collect from a landline.
Hope this helps 😀
Cheers
