<prompt> Human: I work part-time at my university. I went to my relative who does tax work for a living, and he filed my taxes for me. Im assuming that this phone call was a scam. What do I do to make sure my bases are covered?UPDATE: Thanks for all the advice guys. I assumed it was a scam since I never got any mail correspondence. You guys are awesome.  <response>: They send letters. In this hideous 80s-era typewriter-esque font.If you have a lot of patience and okay-to-great people skills, you might be able to get ahold of your case officer on the phone. Maybe. Or maybe if your dispute is higher-valued than mine were. But they wont ever just call you.
