The time slots they give you mean nothing at all. The drivers constantly call that they will be there early (which is annoying as I have to plan when to be home due to work) because they apparently finish early. I'm sorry but if I have a time slot from 3-5 pm how come the delivery guy finishes that day at 2pm?!?! Incompetent and unprofessional. I once also received a text message for a delivery slot and the driver never showed up. I've send them an email informing them about the issues but they have never replied to that email. If I could I would give them -5 stars I am baffled how they can even call themselves a deliver service.
