bad bed bad service

i have complained for the 2nd time in 2 years with no luck... no response from Rachel who keeps saying she cannot get hold of me. the king size bed was purchased cash years ago.... neville at dial a bed can find me on my cell at any time but Rachel at sealy head office keeps dodging me... these beds are supposed to have a 10 year warranty... but the product is really bad i will never buy another sealy bed again
