After sales repair

We bought a Samsung Toploader washing machine year and a half ago.Up until 2 months ago.We have had problems with the washing cycles of the machine.The technician told me it was the motherboard and replaced twice,claiming that this was the fault!!<br> <br> I mentioned to the technician that was a mechanical problem and he said its not possible !!<br> <br> I have contacted the customer service team and reported this. After the 3rd call out of the same problem this item is still not fixed!<br> <br> I contacted the customer call center ,to speak to a supervisor,was told that I would get a call back at 10 o clock on the 13 June 21015,its now 11 o clock and no call!<br> <br> I am now pretty fed up and disgusted that company like Samsung has no regarrd for there customers and they need to sort it out!
