Many, many years ago, the first income tax return to do after we bought our first house was something a bit new to me, so I decided to use H&R Block. The old gentleman who did it, in my presence, said he had to sent it in to his superiors to review, then they'd mail it to me to sign and send to the IRS. What they sent me contained some pages from MY income and some from someone else's form. The only thing we had in common was that, in addition to our salaries job, we were both claiming $1100 in cash income from which no withholding tax had been taken. Anyway, I received it in the mail on a Saturday afternoon and they said they had discovered an error on a certain pay number and had corrected it. So I had half of my return and half of someone else's. I couldn't contact H&R Block on the weekend, and we were getting close to the deadline to file, so I did a return myself and went ahead and mailed it that Saturday. Monday I called H&R Block, told the guy what happened and he said to bring it in and they'd redo it. I told him I'd already filed, but thought they owned me a refund. He said, "Oh yeah, after you have our figures you can do it yourself." I told him I was mailing all of their stuff to him, and I thought they owed me, but that if he thought their forms could be used for anything to just forget it. I got the refund in the mail in a few days.
