I'd be interested to know what Google Maps' web interface returns when you input the same location information. If they don't like your input for some reason, that might help diagnose that angle.

If that doesn't explain it, I'd suggest sending the support ninjas email with screenshots of the relevant contacts so they can try and figure out what's up.

To take a screenshot on the iPhone, hold down the Home button, and then briefly press the Power button on the top of the device. (With the screen you want to take a picture of visible, of course.)

Your screen will flash white - this means that the screenshot was added to your photo roll. You can now use the camera application on your phone to email the photo to yourself, then attach it to a response to this email and send it along.
