We value accountability at Waste Management. If a customer sent a formal complaint about an interaction with you, how would you handle it?

"I understand that Waste Management has put a lot of work into building these long-term client relationships. If one of your clients complained about my communication with them, I would take full responsibility for my actions and issue an apology. I would also be open to feedback to avoid future incidences. Rest assured, in my 15 years of employment, I have not had any clients complain to my employer about my work ethic or delivery of service."
