Unsatisfied customer...please change my mind!

I am really dissapointed with the customer service from them. I had my washing machine send back to them for the 4th time this year with the exact same fault. This after replacing numerous parts including the pc board twice. I get that some faults are probably over their heads, but why must I pay for their studies. The thing that makes me the most upset is that they don't communicate. I can send messages to the rep requesting feedback, and he couldn't be bothered. When you eventually get hold of him, he promises to phone back..yeah right. I wish they could focus on customer support and feedback.Get your house in order!
