Stinking customer service

I was just on the phone with a very rude consultant from your customer service. I made a complaint regarding a brand new Sealy Argo, that is only 5 months old. Sleepmasters did not bother to follow up with me, so today I contacted Sealy customer service directly. The lady explained that they will send me a new mattress and that it was approved. I contacted sleepmasters to confirm with them as to when I can expect the delivery of the new mattress. Your consultant Nala or Nana, is very rude, asking me who told me to phone Sealy and if I spoke to Sealy than I must continue with them. Very unprofessional! First of all, the quality of the bed is terrible and than customer service is worse. I'm disappointed, I want my money back, R6000 later. Worse people to deal with! SM-SEAL-***.Im ****ed off to say the least!
