Absolutely useless

We ordered a bed (electrically adjustable). We got notification that the bed had left the warehouse. A week later, it still hadn't arrived. Upon numerous phone calls, they were unable to locate the bed. When it finally arrived, I assembled it as per instructions. The bed did not feel safe, as the electrical base kept sliding off the correctly assembled unit. I asked for their technicians to assess this, as this was clearly not right. It took again numerous phone calls to arrange this. When they finally arrived, it turned out that several components were not required for correct assembly of the bed. Their instructions are useless/incomplete, and their customer service non existant until threats are made. I also emailed them to refund me for the unnecessary components, but, not surprisingly, they have not responded. NEVER going to purchase from them again.
