3 Day Blinds Wrong blinds-no refund Nationwide

I had a Design Consultant from 3 Day Blinds come to my home. I had one specific question about the operation of the blinds. I wanted to be sure that I would be able to tilt the blinds up or down to redirect the sun even when partially open at the bottom. She assured me that this was possibe so I placed the order. Upon installation I discovered that the blinds cannot even be opened when not fully extended but they also cannot be tilted up at all. She was completely unfamiliar with the operation of the blinds. 3 Day Blinds refuses to refund my money for blinds that are useless for my purposes.
