Firstly, their customer service is deplorable at best. They only have people there to say no or we cant help, or it's your fault.
I ordered atomic wings for lunch for pickup. When i ordered it said my discount was applied and all was good. When i looked at my account they charged me the total amount! When i called to get it sorted out (as any legitimate business would do in this instance) they said well that store specific coupon is only for first time users. Im like, but the coupon said applied. It even showed me the total amount of my order with the discount(i even printed this) then went on to charge me the total amount. Even if the coupon was for first time users only, supposedly, the website that's owned by grubhub/seamless cannot differentiate between a valid and invalid coupon! So your telling me a completely web based business can't even do that remotely right? They told me and quote "you should've read the small print, we're smart enough to put that". I was so outraged i had to just say good day, end the convo, then proceed to call chase and dispute the charge. Just save your time and do that because that's the only way you'll get any money out of them.
