Poor Service and Quality of product

Bought a 43inch smart tv. Not so smart. Inferior plastics etc speakers distorted from the start! Techie came out, opened the tv and confirmed the speakers are shod. It is niw a month later and the speakers have not been replaced. Furthermore, the technician stuffed up the inter interface and now I am sitting with a total worthless item. Aftersales service is pathetic. Rubin Ruiters promised to sort out the problem howerver, I am getting no joy.
