Disappointing experience

I got a washer/dryer combo machine in Dec 2014. It has had an intermittent fault which after countless technician visits from Samsung as well as Hirsches, where we bought it, the fault remains. I am now waiting for a second technician to 'assess' the machine as the last one did not hand in the report. Its been months of frustration and totally unnecessary. You never get to speak to the same person and the call center could not transfer me to anyone in authority to help solve the problem sooner. I expected more from a premier brand. Very frustrated, angry and irritated. My favourite part was when the call centre told me to 'be patient'. I have been waiting for MONTHS for a resolution!!!
