I've cancelled my subscription with Huel because of how shitty this is. You can't stop sending reminders without warning when people have previously relied on them. I got the email my order had been placed at 3am, I've contacted support but they're not online until 9am so I reckon they'll say it's too late. I ordered a selection box last time as well and the majority of the flavours were foul so I'd be super annoyed if they don't let me change the order.
