Delay in SC 189

I have submitted my application of skilled independent visa subclass 189 since 8/2/2017 and paid all fees and updated all documents and finalized my medical assessment. Util now the application status is received. Note that on 30/3/2017, the immigration department sent the uploaded Hr letter to my company for confirmation but this letter was old and so the company replied to the Australia Embassy in Egypt that this letter is not recognized by the company, then the Embassy asked me to prepare an updated letter, after that I sent an updated one to the Embassy. From that date there is no response and no change appeared on the application status. I would like to know what is my situation now.?
