There was a change in the scheduling of Wheel Trans (run by the TTC in Toronto for disabled people - I use a walker and use Wheel Trans on occasion).
The riders AND the drivers were complaining. I admit that I was one of the "complainers".
Did talking about it do anything? No! So after I made my one complaint out loud, I did something - I took action. I called Customer Service (and waited on hold for 30 minutes) then changed my "pickup" times.
I'm much happier with the new times (they're better than what I had before for months!) - better times AND I did something and didn't just talk about it.
Marketing Tip: A change is both good and bad. Communicate your changes and do it in positive language - emphasize the good.
