IRS and the Interest Deduction

You aren't going to believe this! So I have a few hours this morning so I call the 800 number listed on my letter. You have to go through a lengthy phone tree making all kinds of menu selections but it wasn't too bad. After about five different selections I finally get to one that allows me to go to a real person if my question was not answered already. So then the hold music starts. After not more than 2 minutes on hold an actual real human answered the phone. He was able to pull my account up and see everything on his computer. What had happened was the received my letter of explanation, but the bank statement wasn't attached. So I'm guessing at the IRS they have automated letter openers in a secure room because of all the dumb things people send to the IRS, and someplace between the letter being opened and it getting to the auditor the bank statement got lost. So I tell the guy I can send another copy and he says no need for that. He asks me the name of the bank, what the loan was for, and how much interest I'm claiming. He didn't even want the account number. I told him the info and he said he updated my account and I don't owe any money and I'll receive a confirmation letter in four weeks. The entire phone call was about 10 minutes.

So what are the bets; Do I actually get a letter saying everything is fine, or do they send me a letter asking where my check is? I guess I'm just a skeptic. I've called the IRS before with issues and never got anything resolved that fast. Is it possible the IRS is actually efficient now?
