Oh dear! I'm sorry to hear of your troubles! Did you receive any notifications while abroad about excessive roaming? It's possible your account may have been flagged as such. I would have thought that you could still reach out to 611 from the phone, though? If not, definitely contact T-Force via Facebook or Twitter to have them check your account status.
Have you reached out to our care folks to get your service taken care of? We certainly wanna make sure we get you service with us so please keep us posted.
Have you been able to get your account taken care of? Please let us know. Thanks.
