POOR POOR QUALITY 2 REJECTS IN 6 MONTHS

I bought a base and matress set for R7000.00 in September, from November I have contacted them about problems with the matress, after many promises from the Regional manager at Bradlows they delivered a new matress in January (only one guy delivered I had to help offload and load the reject) After 2 months I have encountered exactly the same problem, it's been 2 months now that I have been struggling for them to assist, on Friday a very rude guy from Restonic phoned me and said he want to come and inspect the matress. I am fed up, now they claim that if there is any marks on the matress they won't exchange. I don't even want an exchange this is the second REJECT THAT ONLY LASTED 2 MONTHS FOR R7000.00. POOR POOR QUALITY AND SERVICE!!!!
