I have 2 phones registered on my bill. Both with the $15 Canada-Wide Plan but one of them with an add-on of unlimited text. Recently, for no apparent reason, that add-on has been removed and I am being billed almost $200 for this month and last months messages. What can I do to get the money spent on messages that should've been unlimited back? Why was that add-on removed and how do I get it back too?
