Sealy Grande

I bought sealy bed Grande at OK Mount Frere during Black Friday, in 2 days it had already has a hole , I went to report it at the store. They told me to wait for sealy to reply to them it’s been 2 weeks already and the bed is making me sick , I wake up with back pain everyday. If I knew sealy beds were like this I wouldn’t have bought it in the first place. I was sure I’m buying the best brand little did I know. Now I’m suffering.
