Order mess. We have been dealing with Sleep Number since Oct. 3 for a replacement air chamber. First we were told it would be a week while they upgraded their computer system. Finally received an email back on Oct. 11th. We requested the air chamber at that time. On Oct. 14th we received a response that they would ship to the address we provided. We followed up again on Oct. 22nd and they apologized again saying they were shipping it then. Just called to follow up and was told the order was placed on the 22nd but the product is on backorder with no dates available. Was told a Supervisor could call us back but the turnaround time for that is days. Worst Customer Service Ever. We are paying for a bed we can't even sleep on. We never would have bought this product if we had known.
