I just upgraded my phone online and realized that my shipping address is incorrect. Could someone please assist me in correcting it, before the order is shipped.
I would suggest you contact customer service to see if they can fix it before the phone gets shipped.
If it does get shipped then you would have to call the shipping company which I believe Fido uses UPS and have them put a hold on the package.
You can reach out to Fido's customer service through any of the available methods listed here.
