Eat24 does a lot of things, including pissing off restaurants to the point where you have to talk them into not blacklisting you because they don't call or email if you use Apple Pay for an order with a special request that requires adjustment of the total. I discovered this on a day when I'd just got back from an exhausting conference and really didn't want to deal with anything beyond eating something and going to bed. Thanks, Eat24!
Eat24 also really sucks at handling account cancellation/deletion requests, above and beyond the degree to which their customer service has gone to hell since the Yelp acquisition. I've been trying to cancel and delete my account per their privacy policy for almost a week now, and oddly enough, it's become impossible to get anyone to respond via email or website messaging. So that's more time wasted and frustration added. Thanks, Eat24!
