Shoppers Drug Mart

First off... I have never filled in anything like this before, however, I was so agitated by what just ocirred about 30 minutes ago. I was with my daughter... Had 3 items (razors, face wash, candy canes). I was using the self check out as I always do and one of the employees, very frantic... Was in my face about scanning my optimum card (I never forget). I explained to her that I scanned it already and I appreciate her enthusiasm... But i'm fine. She then starting pushing buttons on the screen to "make sure" and instead... Redeemed my points. I had zero interest in redeeming them as I always save them up for a large purchase at some point. She then tried for about a half out to fix her mistake. The store was packed, people were annoyed, she had no idea how to remove the transaction... So I just said, "fine" don't worry about it. But next time... Don't touch the screen when someone is paying and interfere unless they ask for help. So I lost my 10, 000 points and left extremely frustrated. My daughter then ended up late to her dance class. I would at minimum appreciate having the points put back on my card or for that matter would appreciate "something" for an incredible inconvenient experience. I am including the receipt so you can see exactly what occurred.
