You are not alone. Similar problem here, only more fupped up.
Did you send your 1040 and W7 to Philadelphia? That is where you are supposed to send it if trying to get a ITIN number, but it won't do any good, I think this is where they send the mentally challenged IRS drones.
I sent mine in and get a letter back that because I didn't file a W7, I can not claim my daughter and her child credit was not allowed. I called them and was told that they had no record of my W7 (the idiots LOST IT).
I made copies of my 1040 and W7 and sent it to them with a letter explaining that I DID file a W7 and was enclosing COPIES of BOTH (I also stapled the W7 at all 4 corners so they would not lose it). The morons sent everything back (with the W7 copy severely torn from being ripped off of the 1040) because I DID NOT SIGN MY 1040 and it could not be processed until I did!!! It had "COPY" stamped on every page! They have already sent me my refund, so they have to know I already filed, but the retard that processed my papers can't read English or look up the fact the I already filed.
Oh well, on to round 3
