I can verify that wowdollar is one of the most legit company out there as they have paid me, no I am not paid to advertise for them.

Conversation went fine as you can see, this is from today though. The message yesterday was about renting a 69 rogue ( they treated it as a 70 and would level it to 70 for me). 12$ a day with a month of game time added tomorrow, and they are true to their word, they did add it for me + 12 bucks as you can see in chat above.
One important thing is to RENT DAILY , DO NOT have them pay you weekly. The reason is because you may get banned at any moment AND at any time, and if you do, they will not compensate you OR pay you, they will probably just ignore you like the rest of the companies ( if you get compensated, great ).
