Faulty bed

I bought a bed from Sleepmasters Jhb store in January 2025, the mattress started to make noise within 6 months and I reported the matter at the store, i was told to write down my details and i will contacted, to this date i have not received assistance, i went back to the store in January and in February 2026, i was just told to wait fora WhatsApp and a call from the complaints department however to this date no one has contacted me, i am not happy with the service i have received, the bed is getting worse every day. The bed has a 7 year warranty but i am suffering with a broken bed because Sleepmasters doesn’t care about their customers
