Moen Oakville Canada has been contacted. They claim I need a cartridge and an O ring for our kitchen faucet. They will ship parts. Moen took our phone number and email address. Not having heard from them I called The phone number on the website was an 800 number.....seems like a USA number. When i phoned a local number (905) I got their message. They acknowledged our phone number. We will be contacted. Due to Covid, I realize there will be delays. However going by their website reviews their Customer Service seems to be wanting. Now I know why you have this website. So we shall be waiting and waiting. In the meantime the faucet keeps leaking! Exasperated ! Thanks. Tony
