Empower Professionals Contractor interview questions

What a mess! A recruiter from this company contacted me about an opening for a contract position. Considering the recruiter's command of English was a little less than adequate, I wasn't sure at first if this was a phishing call. Later on, this recruiter ignored crucial information I provided him about my availability, called me 5 times in 30 minutes while I was driving and scheduled an interview during a time I told him I wouldn't be available. I asked to reschedule, but they are not acknowledging my calls. Another recruiter pitched this position to me, but I had to tell them these guys got to me first. Now it appears this job lead has been mucked up and gone to waste. This is not a company I would trust contracting through,
