Ok so, go to a website like
example
wow power leveling|WOW Gold|wow powerleveling|world of warcraft Powerleveling service
So on there website they offer a "PL report"
They tell you the PL id's in it
tell them that you are somthing like
US-CP-E200864172746****
And that they changed your password
They will say somthing like
You are
US-CP-E200864172746****
account name: xxxxxxxx
account password: xxxxxxxxx
At this point change the password
Tell them your password wont work
then kinda stop speaking with them,
This has worked about 2 times out of 5 for me
