Bad service from Ericsson Mattress and Pine , and Sealy

I bought a Sealy EX Length mattress with them and the quality of the mattress was not good, I have logged a complain and to date nothing has been resolved, I always have to call for follow up, but nothing is moving, it takes them a 3 to 4 weeks to get someone to contact me, I am disappointed with the service , please check reviews before making any purchases
