Hello MICHAELQR,
Welcome to the community!
Sorry to hear you've incurred data overage charges. However, why do you feel that you were unfairly charged? You noted that your son used the data.
If you are concerned you were not notified of the usage, I believe that with the older tablet plans, customers would only be notified once $50 in data overage fees had accumulated (see here). That said, most tablets do not have text messaging apps included to receive those notifications. However, since your overage fees did not reach that threshold, you would not have received notification of overage usage. It has always been the customers' responsibility to monitor their device's usage -- even if someone else may have been using the device.
I understand you are upset with Fido regarding this matter and are considering other providers. However, all providers would treat the situation the same. The additional data was used and therefore incur additional charges.
You should note the forums are community-driven and not intended as a venue for customer services. We would not have access to customers' accounts nor be in any position to assist with your matter. I understand you have already spoken with the, however, if you want address your issue, you would need to contact customer service again. 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
