Api returns wrong zipcode by address when house number has letter


I see that when I see a address by a organization with a letter like streetname 112A, 1234AZ city, netherlands it does not always returns the right zipcode in api. Looks like it returns the zipcode of the beginning of the street instead of the number.
When I remove the letter from the house number the correct zipcode is returned.

I think we can blame google for this bug, was checking it in the api I get the same results back. only not sure how I can report this bug to google.
