To whom to report if somebody salary credited to my pan

Thanks for your reply, the problem here is, Somebody is using my client pan number without crediting salary to his bank account. Central govt employer is deducting tax based on my client pan number ,even though he is not the actual employee

if you don't know about deductor.........who is doing such mistake
you can find information about TAN of deductor from Form 26AS
and thereafter , you can approach to such person for further clarification .
