Don't buy a Whirlpool.

I reported my dishwasher to them on June 5. They delayed picking the machine up. Then after they picked it up, delayed giving a quote. I paid immediately. They delayed returning the machine. When they returned it, the machine was not repaired. 3 months, 20 emails and many phone calls, I've no idea where my machine is. I get no return calls. No response. No answers. It's now 3 September. What do I do?
