Restonic bed, worst make ever

Worst bed ever. Bought a restonic bed set from Bradlows November 2020. Not even 6 months later the mattress completely collapsed. With a huge fight I got hold of Restonic and after many fotos and videos they replaced the bed set. The replaced one did not even last three months, the mattress collapsed, the mattress makes so much noise. For the last three months I have been contacting Bradlows and Restonic, by phone, e mail, and watts up, as we had the agent at restonic cell number. No response, we can see he reads but does not reply. We have not hadva good nights sleep in months. We now saved to buy a sealy mattress, I hope this goes better. Never by a restonic, it is the worst bed ever, and the after sale service is just as bad.
