Bad service

I am extremely disappointed with the lack of service from HiFi Corp. I purchased a Sleepmasters Camelot MK3 (Order #***) on Black Friday 2025. After only a few months, the mattress is defective—the internal springs are protruding through the comfort layers. I have sent multiple emails to both HiFi Corp and Sleepmasters (JD Group) but have been completely ignored. Under Section 56 of the CPA, I am entitled to a refund or replacement for a defective product within 6 months. I am still waiting for a reference number and a collection date. I am posting this as a final attempt to resolve this before escalating to the Consumer Goods and Services Ombud (CGSO).
