After you file

I was unable to file electronically because my return kept getting rejected because the AGI was supposedly wrong event though I got it directly from the IRS Transcript.  So then, I filed by mail over 8 weeks weeks ago and the system says the status cannot be determined.  I have called the IRS almost daily for over two weeks and cannot talk to an actual person.  How do I find out if they even received my return?  It is so frustrating.  Any ideas how I can either talk to a person or get status?
