From my experiences with AC over the years, and I have had my share of problems, something doesn't add up. But then again, only getting half the story typically presents that problem.
Canadian there is no way AC would treat you as bad as you continually allege and still be in business. Everyone has a bad day but they do not pick on customers. If they did lawyers would have a field day with them.
That is why I think we are missing half the story.
