I want to talk to a person when I call, not a machine. I have bypassed many service companies that only have an answering machine or voice mail.

If it is an in-house service, show up when expected. At the very least, call if something comes up.

Do the best job possible. Explain without treating me like I'm totally stupid.

Like anyone else, I'd love to get a discount. But I'd rather pay a little more for good service. I'd stick with a company that respects my needs.
