Not happy with sleepmasters

I bought a sleepmasters Toledo 152 cm base set on the 30th of April from bradlows Dundee kzn , within 6 months the mattress is poking me , it shows wire that looks a rassor on the side that cuts me when I'm climbing on, its actually not worth R5500 I paid for it even looks cheap . This mattress is hollow inside judging by how light it is, it will never reach that 10 years warranty they gave it failed to live for even 6 months . I went to bradlows they filled a form ànd told me someone will come to see it but nobody has came yet that means I have to bear this discomfort for much longer I am not happy with sleepmasters as a brand I wish I had bought Sealy or restonic because they are much better brands compared to this sleepmasters
