I told them that they better shape up and if this happens again I will be canceling my card.
I find CIBC great with regards to suspicious transactions. You can register on their site to receive an email "credit watch" or something like that when ever a problem arises. I have the system triggered a few times this past year and each time had the problem resolved in under minutes.
