After 18 hours I ordered a WOW powerlevel 1-60 to WITHGAMES.COM, Blizzard suspended my account, the reason for it was:
"Type of Violation: Use of Prohibited Third Party software Consequences for Account: Account Suspension for 3 days (72 hours) and warning placed on the account".
WITHGAMES answered me they were surprised with it, they told me maybe it was due to being logged in many hours (they told me more than 24 hours, obviously they were lying, I checked all the time their progress on another account). They told me they were not using programs for cheating, and again it sounds like a lie. I asked them for giving me back the money, at least the difference between level 27 they leveled me up (they began with level19) and the 1-60 I ordered. The surprise was they told me they check me a lot more of money for it, because they needed a lot of time arranging the powerlevel (they started with a 19 twink!!!). So, they gave me back less money than fair price and I get the account banned for 3 days and one warning placed on the account. Some friends of mine told me about the same thing... Conclusion... if you want to raise your level... spend hours by yourself of trust in some confident company.
