how do I get Siri to find my business for customers

I am trying to get my business on Siri's radar. I have my business listing on all search engines, nothing but good reviews, high on other search engine rankings but when I ask for businesses in my area that offer my service Siri gives me 4 other companies with no reviews but not mine. How is Siri finding other companies with no reviews but not finding my business which has high reviews? I wonder what they are doing that I am not.
