Sleepmaster n Sealy sell poor quality

I bought an Evougue king bed at sleepmaster n started to sink within 2 weeks. I went to de shop in Hemingways mall in East London n I was advised they will take my matter further to de company. Till today still waiting n still sleeping in an un even bed. I've been buying sealy bed trough out my life but now I seem to regret n would advice anyone to look for a different brand
