We were in a similar kind of situation sometime ago, but then the AVM changed for us saying that they have sent a notice for some more evidence required(RFE) and we should recieve that within 14 days. We never recieved it, then the message changed - it said "The notice was returned from the post office saying that this person doesn't lives here". We were shocked and surprised, so we called back and they said they will resend it again. So now the new AVM message was that they have resent it and should recieve.... etc etc. Again we never received it the second time too. So we really don't know whats going on, are they really sending it or what... We get all our other mails, utility bills etc at this address where we have been living since almost 3 yrs now.
Let us know , if anyone else has been thru this kind of situation. Thanks for any kind of information or help provided in this matter
