Bad service from OK furniture Eersteriver

In December 2024 I bought a Sealy bed for R5000. Then after the first night of sleeping on the bed there was a big hole in the bed, now bear in mind I only weigh 65kg. After contacting them they told me that I must rotate the bed, I mean how do I rotate a bed everyday after sleeping on it. So I wanted my money back. Ever since it's been up and down with them. I'm sitting with a bed I can't sleep on while they just refuse to refund me or even exchange the bed
