H1 B visa

Hi ,

My employer applied for H1B visa in April 2015 . Till date we have not received any update from USCIS . The attorney says that they have not received any receipt or specific update regarding my case . Also they have not received back the application from USCIS.
Does this mean my application was not picked in the lottery or could there be a delay in receiving the recipe number ?

Please help advise.
