Sleep Number review: Bedding shipping and account info

I ordered a new set of sheets about a month ago. We received the wrong size and bed type. I called and spoke to a rep who charged me $7 to get a label to return the incorrect sheets and get a new set sent out. The new set arrived and was again the wrong size and bed type. I called and spoke to another rep who did not charge me for the return this time but sent me another set of sheets. She also put in a replacement order for another set that we had used once, and they ripped. So, we were expecting two sets of sheets. Once we paid for and one replacement under warranty. AGAIN, we got the wrong size and bed type for the set we paid for, and the other set were sent to our old address. I called again and spoke with another rep who put me on hold, put in a new order for the set we had ordered and paid for (the only way we knew this was the email that came through shortly after being put on hold) and never returned to the phone call after holding for 20 min. The new order came into my husband's email, but it too was being sent to our old address that we have tried to update numerous times but can't seem to get it to stick. Had the rep come back on the line we would have told her this and made sure she sent it to our current address, but she never verified anything with us or spoke to us again. We called back and spoke to another rep who was finally able to update our address (apparently it had a start and end date set in the system that would not allow the address to update permanently) and then put in a new order for the correct sheets one more time. We had the replacement sheet set resent to us at the correct address. She did not ask for the incorrect set to be sent back this time, so we still have this set sitting here serving no purpose. Today we received the set we ordered and paid for (for the fourth time) and AGAIN they are the wrong size and bed type. I am not sure if we will see the replacement set for the ripped sheets or if they are coming to us here. I won't hold my breath. We ordered a California King, FLEX top but keep getting sent King SPLIT top. I don't know if the reps don't know what they are doing or ordering or if someone at the warehouse isn't paying attention, but this is getting ridiculous. When a set of sheets costs almost $300.00, and no one can seem to send the right sheets, it is a HUGE inconvenience to your customers who spend countless hours on the phone with support and have to package up and send back sheets over and over. This is not how we envisioned doing business with a company that we spent A LOT of money on a bed. It was like buying a car and yet we can't seem to get sheets. THis is not the first time we have gone through this. This has happened two other times in the past few years when ordering sheets. How is it that no one can seem to understand the difference between FLEX top and SPLIT top and KING and CA KING? I am so disappointed and we have still not received the correct sheets, the replacement sheets or a refund. I want someone to address this and make it right or I am going to contact Melissa Barra about this. You should have customer service trained on what they are ordering and warehouse employees trained on what to pull off the shelf.
