After you file

I filed my taxes 2/1 with jackson hewitt office. It was accepted. Then I had to verify my identity, which I did 3/1.  It is now 4/20 and I still dont have my refund.  I got a tax advocate involved. She gave them until 4/19 to have it finished, but I got a letter in the mail today, dated 4/19 saying they needed an additional 60 days to work on my refund and send me a complete response to what action they were going to take on my account? What the what? I have verified my identity, i have verified and proven my income. I have no garnishments? How can they keep doing this. And since they tax advocate only gave them until 4/19 to have it complete, how can they say they are taking an extra 60 days? I am beyond frustrated.
