Sleep Number Bed - Select Comfort Review

I purchased a sleep number bed and I actually loved it.  I had to return it because my sales person misled me about the sale.  Select number was running an 18 month no interest promotion so i decided to buy a bed.  The sales lady ran my credit and said i was approved. After I received my notice of my first payment I saw that I only had 90 days no interest. When I called Select number customer care they said I had to be approved on the GE credit card, somethingthe sales lady never told me. I called our sales lady and she said that she was sorry and would try to fix it and get me the 18 month no interest and would call back in two days, its been almost two weeks and heard nothing.  Once again I called select number and after talking to them they said she cant change the terms that once the credit company has the account its out of their hands.  So I think the sales lady was trying to get me to hold out until it was to late to return it.  I had to pay 170 dollars to get it delivered and now another 200 to get it out of my house.
