10 Free Meal Fiasko

I used a coupon that was supposed to get me 10 free meals. However it charged me for the order after applying only a discount. Initially it only asked me to pay $1 dollar which was ok, but then I saw my card was charged $35 3 hours later. I didn’t accepted this charge. I didn’t wanted this food in the first place, I just wanted to grab my free stuff. I canceled my account imminently.
