How much does your effectiveness as a dissatisfied customer depend on your willingness to suspend your relationship with the business?

For example, I drive a Prius. I probably couldn't sell it now anyway, even if I wanted to, which I don't for a variety of reasons.

I suppose I don't enjoy speaking to people dissatisfied with my services, but I aim to please when things aren't right. I expect that from my service providers. Sometimes it seems they are unaware of the problem.

I feel like I've been complaining a lot lately. I'd love to hear any of your advice on how to be heard and maintain your relationship with the service provider.

And what if the service provided is to your children - their teachers, coaches, directors?
