Purchased a Sleep Number Queen C4 360 smart bed. Nice people, but the first red flag I should have balked at was when they said we had no choice but to use their deliver/setup people, which would cost $200. If this is not optional, then why isn't it just included in the purchase price? Secondly, after purchasing the mattress and ultimately deciding it wasn't for us, my wife called the company to arrange the return, and was told that we would be refunded the purchase price minus the deliver fee ($199 plus tax). Okay, not happy with that, didn't know that up front, can't seem to locate any actual signed paperwork stating that (it is on their website), but okay, I'm willing to let it slide (actually I hate it). But now they are trying to change the invoice information somehow and pretend they are refunding us the aforementioned amount of money while still somehow holding onto an additional $242.
