unprofessional service

Store Manager has treated me like an unvalued customer, after reporting dissatisfaction with how an ongoing issue has been handled by 1 of his staff members, Charmaine, he has given me the same if not poorer service. 8weeks have passed with my issue of a faulty base not being resolved. I was promised feedback and step by step updates of how my complaint was being handled and resolved, instead, I have received only 2 calls from Werner, since the 25th, when I had escalated the complaint to him. I am at a point where I am now suffering from backaches as a result of sleeping on a concave bed. 8weeks of no action from Joshua Doore. Is this the kind of service awarded to all consumers by this store?? Must customers have to be rude to get the necessary assistance? This is a serious violation of my rights as a consumer, not to mention my human rights.
