I tried for the last 2 weeks to get in touch with NAPNES for my pharmacology certification but is impossible. If you pay them you might have the chance not to get the certification because the id and pass they send you doesn't work and if you call them you get a voicemail. They never answer to any emails or phone calls. I just waisted $100 for nothing. Do it at your own risk. THey have the CASTLE phone number on their website and if you call them they give you the NAPNES phone number. It is pointless. I regret that I did that with them.
