Rural King review: Hiring procedure

I have applied at my local Rural King more than once and have never gotten an interview. The last one was for a part time cashier and I feel I was qualified. My work history is impeccable, having retired from 37 years with my last employer but Rural King wouldn't even give me the courtesy of a job interview. I'm a veteran, have good health, live just down the street and have been a loyal customer since moving here two years ago. When I stop by to enquire as to my application I get the "don't call us we'll call you" treatment. I feel I'm most likely being discriminated against because of my age and the fact that when I speak it's obvious that I'm not from here.
