They've delivered the mattress to the WRONG address on the WRONG date and simply dumped it outside the door. This was a week ago and it is still unresolved, despite me calling Bensons for Beds (which uses DX for some strange reason I cannot fathom) multiple times. No way contact DX, no pickup arranged despite its urgency as I'm moving house at the end of week. Absolutely livid. Avoid at ALL COSTS.
