Defective bed sold to me!!!

Bought a really expensive bed on their website as they were promoting specials which were great! Then ended up getting a defective mattress, which i complained about, Sealy the manufacturer confirmed the mattress to be defective and said I should get a replacement from Dial-a-bed. While I have to no2 wait for a replacement and sleep uncomfortably, dial-a-bed simply apologized and blamed Sealy...Not even offering me an appropriate apology and not offering me a compensation gift of apology or any gesture! Its such bad business, did they simpl think sending out a defective mattress in hopes that I would simply not realize or was it because it was in special that I now have to suffer!?! A replacement is great yes, but I feel due to their negligence or intentionally sending out a bad bed to an innocent paying customer that I should be compensated in some way other then them simply shifting the blame to the supplier! I was the one who purchased a bed valued at R10'000.00 and got dooped, now I must just accept that dial-a-bed is not to blame and Sealy walks away saying oops??? This is such a bad experience I have had to pay for, I am in shocked and disgusted by the brush-off on both parties.
