Bad after sales service from Sealy SA

I bought a Sealy adjustable designer king bed from a distributor BEDROOM BASICS in Cape Town who has subsequently closed down. Sealy provided two remotes of which the plastic covers have since deteriorated to such an extent that I can no longer use them the. The plastic has become so sticky that it picks up dust and uncomfortable to use. It’s as if the plastic has melted and is dirty. I have been struggling with Sealy SA for a replacement since 18 November via email to *** and phoned customer care for which I have received no response also Facebook who has referred it to head office but also that’s where it ended. As of today 03 December 2024 no response from Sealy SA
