Pathetic after sales service from defy

In September 2014 I purchased a Defy Max **** 800 washing machine from House and Home Lenasia, ever since I purchased this machine I have been having endless problems, when I went back to House & Home Lenasia they try to pass the buck, they say they will send out a Defy technician, when the technician comes out they dismantle the entire machine and stick parts together with double sided tape, they leave saying the machine is fixed however when we use the machine again the problem persists, the technicians have come out to my premises about 7-9 times and the machine is still giving problems, I have spoken to the branch manager at House&Home but it seems like he doesn't want to help me, he keeps saying that he is waiting for feedback from Defy. I even bought a Defy Eco 266 liter freezer which was not locking, we are still waiting for someone to come out and fix it too. When I call House&Home Lenasia they do get back to me, I have to take time off my job to go into the store to get feedback, they are always waiting for Defy for feedback, the service is pathetic to say the least, have these people not heard of the CPA, I want a refund and will never buy another Defy product ever again
