Disappointing Service

i purcased a washing machine early last year and the machine is still under warranty. i started experiencing problems with the machine especially when i would use the spin and rinse function. i called to complain about it and was told that and agent from Defy will attend to my problem. i was then contacted out of the blue by this agent that he is at my gate. to my dismissal i told him that no one is home as we are at work. he continued yelling at me [i have recorded calls] i arranged my neighbour to go to my house. after that i heard nothing. no feedback at all and i machine is still not working. i find this appaling and did not expect this service from Makro. this is certainly my last purchase from Makro.
