The caller I.D said Skype however when I called them back they told me they were the I.R.S. (With an EXTREMELY thick Indian accent) and when I called him on the fact that I knew for a fact I owed the I.R.S. Nothing; and due to seizures have been disabled for several years, and that those little details should be available to him since my aunt worked for the I.R.S. For 35 years he quickly hung up on me. After several more calls to them with similar results (hanging up) I quickly deduced these people are up to shady doings so I asked for a supervisor and was told by one lady "We don't have supervisors here," and I told her about my aunt who retired as a supervisor, and was hung up on. My next call, lol and behold! I got a supervisor! Who hung up on me when I pointed out the Skype caller I.D. And the fact that we're not informed that we're calling the I.R.S. When we call in... Shady goings on my friends, especially when he told me that they wanted to sue me rather than audit or discuss payment arrangements, and not even any written letters from the I.R.S.? How gullible do they think we are? And the lady I spoke to really needs to work on her valley girl accent, I could still tell she wasn't nowhere near American...
