Received a call threatening legal action on a supposed credit card debt. Address was incorrect and the debt originated in 2012. Told the man I had no such debt in my awareness, nor on my credit report. Was informed that he would take note and that they would have no options other than to proceed with litigation before hanging up on me. I called back and said he probably needed my address, to which he claimed he already had it, rattled it off, and when I went to verify the information he had provided, I was instructed to "clean out my ears, stop wasting his time" etc. After that, I told him I appreciated neither his attitude or scare tactics, to which I was taunted about being scared, mocked, then hung up on again.
