All gone?
I had the same issue with my card being compromised this morning. The interesting thing is I didn't get any email notifications like I normally would if the card was used or declined. I suggest it's not the retailers specifically but, the clearing or processing centers that is causing this issue.
You realize this thread was posted like a month+ ago right?
My CC was also comprised on Sept 6. $3000 roughly was charged on it. I've been using that credit card mainly for coffee from Tim Horton which has been fine for years. My card was comprised after making some firearm purchases. Some from PR and another from Arms East. So not sure where it may have been compromised.
