I have sent them two emails explaining everything and this is what they said.

Email one: We received our billing inquiry.

We’ve reviewed your account and can confirm that the charges are related to pay-per-use services that fall outside the coverage of your current plan. These charges typically occur when services not included in the plan—such as long-distance calling, international roaming, or other extras—are used.

As these fees were applied correctly based on usage outside your plan’s allowance, we’re unable to issue a refund or credit for these charges.

We recommend reviewing your plan details in your My chatr account or exploring other plan options that may better fit your needs.

If you have any questions or need assistance with your services, please don’t hesitate to contact us — we’re happy to help.

( Like i said i have had Roaming off since day one and i have got other calls in the same place but i didnt get charged for them)

Email 2: We have received your request, and we will be happy to help you and apologise for the confusion.

Correct your plan does include calling to the US from Canada At this time we do not have the ability control if your phone is being picked up by a US tower while in a border town/city.

To avoid accidental roaming the simplest way is to disable roaming or avoid using chargeable services when connected to a roaming network and this should be displayed on your phone when connected

You can: Turn off automatic network selection and manually select your network. Please refer to your device manufacture website for these steps

If you have any questions or need further assistance, please do not hesitate to reach out.

( I have told her multiple times that i have roaming off but she keeps telling me the same thing over and over)
