It's $20.99 because their using bots, nontheless, the price shouldn't entitle them to steal peoples gold.
I can understand why they left guild though.
Hmm, As for blizzard, Yea, i suppose saying you were hacked could work well, since, even if they do investigate, it will appear like it actually was.
Your lucky that's all they took, I purchased 2k gold one time(from some other company), and they took forever to deliver, and they finally decided to deliver it 2 me, however, the leveler guy was on the account, he took all the gold, and denied he did, never got anything back (though, i don't think that was w/ your PL service)
Also try not 2 log on the account at all within the PL time, if you do and they find out, and you get banned (even if its their fault, prepare to receive full blame lol)
Next time, It would've been better to look for a PLer on MD, w/ good rep.
nonetheless, don't get your hopes down, I think i bought 50-58 from those guys, and they successfully finished it,so yea.
