I mailed my taxes 2 months ago, no response status yet

I mailed my taxes 2 months ago after my e-file attempt was rejected. I have not received a response status yet. Track my refund information on IRS website has no data available. My wife changed her immigration status, therefore a new SSN was used this year and not a ITIN as previous years. I'm thinking that could be the reason why? 

 

There is no one available on the IRS phone line for assistance....
