sales person ****!!!

We bought a bed on 27/10, the sales person advised us if we buy a serta bed and anything happens in 8 years the bed will be replaced even if mattress is dicontinued and it was delivered on 28th. On wednesday, we phoned dial a bed to advise them that theres something wrong with our bed, it took them a whole month to send someone out to come and check what the problem was. Finally we were dealing with a company called lylax, the lady there says, the sales people always gets it wrong.Now apparently they can decide whether to fix the bed or replace it! That was not sold to us like that when we purchased it. I phone dial a bed again just to find out what the sales pitch was and lo and behold the guy says the same Thing as the first sales person!Shocking! He says he will have to speak to his manager and will get back to me.... he phones back but now tries and explaines some nonsence about warrentees and garrentees but nothing about what he just said over the phone,.rediculous! And tells me the bed is anyways discontinued so they cant replace it! Now this Lylax company are just fixing the bed that had a factory fault on it.... spring system collapsed in two days!!!! How does that happen?
