When I got out of the Navy (August ‘75) I started college the following week. Income tax time came and I filed as quickly as possible (needed $ for second semester and party expenses). Needless to say, everyone I knew was getting their returns, and I was getting nothing.
Finally, several months after filing, I got a LETTER from the IRS, telling me they had processed my return, but they could not mail it to me because… THEY DID NOT HAVE MY MAILING ADDRESS!
I called the regional IRS office, read their letter to him, then chewed his *** out. He had no explanation for the letter, but he did ask if I would return it - nope.
I got a certified letter from the IRS with my refund check a few days later. Sadly, I lost the IRS letter somewhere during my moving around during college.
