Call 206-684-3000 and ask to speak to Mr. Marshall. I have personally called him a few times and I know my neighbors have as well about the sloppy garbage pick up in our neighborhood. They were even skipping our street for recycling some weeks!
Just tell whoever you get in garbage/recycling collection that you were told to speak directly to Mr. Marshall. We haven’t missed a recycling collection in a while now and the pick up men haven’t left our street strewn with garbage since we all called.
