Constant issues with drivers not following instructions or outright stealing orders. One entered someone else's home to deliver instead of leaving it where requested, and delivery reeked of weed. Blatant false advertising with promo coupons the app notifies you of, as the only one you can use is the most recent--you have tiny windows of time (often only a single day) to actually use the coupons they keep reminding you about. You shouldn't have to contact customer service about EVERY order.
