Purina review: Job

I have applied more than 80 different applications to this company in a period of 2 years but they have never considered me for a job. I hold a bachelors degree in laboratory sciences. I have relevant qualifications with excellent expertise to bring to the table with more than 20 years' of experience.
I eat and drink nestle, my cat feeds on nestle food too. I have done business with purena for years, but they won't hire me. Can someone please explain?
Hr is never available to answer phone calls. What do i?
