Who called from 4154834562

I could tell from the start that it was a scam. He claimed to be from the IRS and then asked me for my name and what school I went to. He then asked if I still live with my parents. I very calmly asked the man what his name was (John Harrison I think he said). I asked who his supervisor was and he told me he was the supervisor. Then I asked who was above him in terms of management. There was a short pause and then he said, "you piece of [***]" and hung up the phone.

I also received this call. Thanks!

Same here, sounded hispanic. What the hell is their end game?

Got called by these people thought it was a scam, so asked for their supervisor. The lady told us that we were gonna get picked up by the local authorities, with 2 years in jail and such. The lady freaking said "I will make you cry behind the bars. I will make you cry, I swear to God." "I will make you see" A little freaked out, gotta say :P The lady finally hung up after making a bunch of threats. Got a recording of the second half of the conversation xD

Oh, also gave us an address, "450 Goldengate Ave San Francisco, CA 94102", which is the San Francisco Federal Building :P
The number was 415-483-4562

Got a message similar the the mentions from other people, stating it was the IRS and to not delay in returning their call.  Of course, I wanted to see what this was about, and like others, I have received tax returns the last several years, so couldn't fathem why they would be calling.  This is a TOTAL scam - don't speak English well, gave me the whole 'they will be coming to arrest you within two hours' talk, and when I told them that I was recording the conversation, they said that it was a part of MTV Crazy Prankers?!  So, if you receive a similar message, do yourself a favor and save yourself a few minutes of time that you'll never get back, after wasting it on them, and block their number (415) 483-4562
