I have turned cellular data roaming off on my phone.

This is one more reason to find a different service provider.

I can’t even schedule a representative callback until tomorrow!

Hi ​@Jvas 

We have reviewed the details and we have been able to remove the roaming charge since it was triggered due to accidental data roaming, feel free to check the details in your self serve account when you get the chance.

We recommend switching data roaming off and also switch to manual network and select Koodo in the phone settings, this would prevent the connection to a US tower when near the border.

For more info about how to prevent accidental roaming charges, please check out this article https://community.koodomobile.com/plans-services-232910/easy-roam-understanding-how-you-will-be-charged-while-traveling-7811296

Thank you very much!

I checked on self serve and the charge has been taken off.

The cellular data roaming is switched off in my settings. Now I can visit Niagara-on-the-Lake without being connected to a US network.
