PetIQ Vet Assistant interview questions

Phone interview, barely asked any questions, pretty much just went over the job description and what was on my resume and why I wanted the job. Very easy and nothing to be nervous for, but I didn't get a chance to really tell about my experience or qualifications to make me stand out from other people besides what was already on my resume. They said if chosen, there would be a 2nd interview and would let me know in 2 days. I never heard anything after my phone interview so I assumed they didn't choose me since most jobs do not end up telling you. Then, almost 2 weeks later I received an email stating they tried to contact me and I didn't answer so they weren't moving forward with me. I replied twice, to 2 different emails saying this was a mistake and that I was still interested in the job and never received an email or phone call from them, and now they refuse to answer me back. It is THEM that will not answer, not me, when I was very interested in this job.
