We ordered a C4 in store and we're told that we'd have about a 4-week lead before delivery. 3 weeks into that, we called to get a status update and schedule delivery. At this time, we were told we had a P5 in the works, it was a "free upgrade" and still had an additional 3-week lead time. We were told that if we wanted to "switch back" to a C4, we'd have an additional 8-week lead time. So they decided to switch our bed and are making us wait an extra 8 weeks when we decide we want what we ordered. They switched our order without notifying us, extend the lead time by an additional 8 weeks, and through all of this, have absolutely zero remorse and desire to make the customer happy. Sleep number leaves a lot to be desired and has a lot to learn about customer service.
