House and home bed

Purchased Mexi Pedic bed in August for R6000, from House and Home, Pavilion. This bed is associated with the Serta brand. The bed is hard and very uncomfortable, totally different from the display sample at the store. I have contacted the store manager, Regional manager and Serta office. I was assured that someone will come and inspect the bed.... to date no one has pitched up. Please be wary of this company, brands associated with Serta.
