A vast majority of my orders are messed up in one way or another. Missing items, rotten produce, raw meat in the same bag as fresh goods, entire order sent to the wrong house, sometimes I get someone else's order, I've had rotisserie chickens with a chunk missing out of them.
And then refunding anything is a nightmare. At first it's easy and you can just do it on their website, but once you return 3 or so things they block your access to the online help and instead make you sit an hour on hold to talk to someone who doesn't speak English.
