After you file

The office from Dallas, Texas I live in Dallas. I didn't recognize the number i thought it was a bill collection place..lol. I answered it anyway and it was a representative from the IRS. They asked for my name and said that my return was completed on April 28th when I called two weeks ago I left my number. They said I should be receiving a letter and my return will be DD no later then the 21st and if not to call them back.
