my demaged Selly mattress

I bought a Selly bed set and the mattress was damaged which I reported and they said for them to replace it I have to pay R1600.00 to Bravo Absa account which I did in 2011.The store was kept on delivering the damage mattress which I had to send them back. I went to the store to make a follow up on what is happening and why are they delivering used and damaged mattress as I'm suppose to get the new one,the store manager was so rude to me and she told me that she is sick and tired of my unresoled dispute and I'm waisting her time that she doesn't have she will call me to make arrangements on when she will deliver the mattress and she will inspect it herself that is not used or damaged as if I am making a story I'm lying. I was so angry I left the store and until today I haven't called her or even their customer service center that failed to help me and I haven't received a call from her,or my mattress or my money up to today, all I wish is to get my mattress or my money,I wish the store management will attend to this as I don't see distinctly different service in this store as they promise or their motto
