First contacted pkarc on 4th July 2013 requesting a refund via private message.  He has been online since then, yet no response and no refund.  Tweeted @hashrackpool requesting the email address as the contact form on the site is gone, got a response within 24 hours.  Emailed the address 2 weeks ago with full details, no response.  Have tweeted and emailed several times since with no response (and he's definitely been online since).

I hate to use the word, but it looks like pkarc is a scammer.
