Sleepmasters/Edblo I need answers

I need some assistance, I bought a queen size Edblo bed from Sleepmasters around July and few days later it started to squeak .

I went to the store to report it and three weeks later I was asked to bring it back. I gave the bed back and I wanted to take a different brand but the sales-lady insisted that I take the same brand. After using the new bed for less than 5 days it started to be noisy when I'm turning. I weigh btn 88 and 90kgs,I really think that these beds either have a factory fault or they're just ****. When I reported the matter to the store in August, I was informed that I will receive an sms from edblo but up until today nothing has been done. I am not sure whether it's Sleepmasters or Edblo but their service suck big time??????
