Horrible service

I brought a Restonic Barbados bedset from Sleepmasters in March 2020. By July, the inner support of the mattress as well as the "marvelous middle" had collapsed. I sent the company an email to express my grudge but to no effect. I phoned on numerous occasions and reached an agent by the name of Kanye on Sunday 26 Aug who went to a lot of trouble and registered the complaint. I would have been contacted within 24 hours. This was a week ago with unanswered emails and phone calls. Stinking after sales service within a few months of purchasing a product with a 10 year guarantee!!
