Bed has a whole barely 2 nights after use

I bought a brand new Seally Argo cash via HifiCorporation, it was delivered by Bradlows, within two nights of sleeping on the bed, it already had a hole. I have reported this matter so many times, and Noone from Bradlows has called me . The only response I got was the reference number, then after I was asked to send the delivery note. Which I emailed. When I followed up on the matter, I keep being asked same thing. They said someone would come and insect the bed, the bed literally has a hole, I'm not even big, it shouldn't be like this especially for a bed that's supposed to be firm. I bought a Seally Reno top for my mom 10 years ago, that bed is still very much intact, this Argo couldn't last 2 nights. The side I sleep in has a hole. I need this bed taken and replaced. This clearly is cheap bed at a higher price. For the money I paid I deserve to be taken seriously. Bradlows must take their bed and replace with a real bed.
