[My account under review why? I am not sure please help me.]

I am a fiverr new seller.  I have completed 26 orders as a new seller.  I started a problem with a buyer's work and I am doing all the requirements like his work.  Then he is reporting my name.  Now my account is under review.  I was not given any warning.  And I haven't received any warning yet.  My account is under review for 60 days.  How can I get my account now?  Senior leaders please help.
