Bango charges me every month for $10 since October on my mobile number. Did not see any subscription nor aware of any app that's associated with it. This is unacceptable as I did not make any purchase nor activated any app and no history as well. Fido told me to call bango, emailed them and no reply. Why do you allow 3rd party billing w/o authorization from the owner? That's fraudulent!
Welcome to the community!
I'm sorry to learn about this incident.
Bango is a service that charges you to your invoice when you make in-app purchases, instead of paying right away with your credit card. This is why you see it on your Fido bill. It's important to note that only the user of the device can authorize these in-app purchases.
Since the charges are from a third party, you can only contest them with Bango directly. You can visit https://bango.com/contact and they should get back to you and assist you with the unauthorized charges.
