Bought a new King Size Bed form House and Home

Bought a new king size bed in Sep 2013, Jan 2015 I complained that the mattress was broken. I was told the supplier will contact me for an inspection. 16 Feb nothing, visited H&H again, promised to phone back. Again nothing happened. 17 Feb phoned and spoke to Sales Manager, received phone call, promised to sort out the same day. I was told to prepare for another R250 delivery fee, whatfor I asked. It is now 20h20 same day, not even a phone call to state progress, never mind another no-show. I am now beyond pee'd. This was my first, and certainly my last H&H purchase. Discusting! Where can I go to get just a little bit of service instead of blame shifting? I demand either my money back, or a new bed!!! Is that too much ask???
