ProtoCafe interview questions

Very easy since I knew all the processes. I spoke with 3 of them. I was offered a job. I was going to pay for my own move unfortunately. I asked about medical and dental benefits since at some companies its $500 to $700 a month. Protocafe couldn't answer this question after my asking several times. Rather than do what any responsible company would do and find the answer themselves and get back to me I was dumped off on someone else. I called and left a voicemail message and this person never called back. I never heard from the HR dept with the onboarding information. I figured if they were that irresponsible why am I going to move from another state for people who can't do ordinary things for someone they extended a job to? When Protocafe got back to me 3 weeks later I told them I never heard from their HR dept nor any reply to my health insurance question. They told me I was "aggressive" and "unprofessional" for pointing out their lack action as well as how many times I asked with no answer from them. They basically said I was a liar about leaving the message regarding health insurance questions. They retracted their job offer and I told them that was fine since I already moved on 5 days after no contact from their HR dept and not getting a reply about their medical insurance...assuming there is any insurance that isn't overpriced.
