How can we submit feedback to Apple about Maps?

It appears that we now have to copy-paste an address into Google Maps in order to avoid using maps. ill do that because I have to. Every time I've clicked on an address and gone to Maps, or opened Maps to use it, it has been unable to find the location. It's not a problem with location services or wifi, it's a problem with Maps. I'd feel better if I could just express my aggravation at being controlled by Apple with a lousy result. Then I might be able to be more patient while they get their act together.
