have been getting calls from this number reporting that FBI reports - then I disconnect, no answer when I call back, very intrusive calling my cell phone with unwanted spam calls.
Be careful, a lot of time that "press any number to be taken off the list" is just a way for them to verify that you are a real person, with a phone, and that you got the call. Most of the time that will get you bumped to another list of contacts for future calls. Better to just ignore it.
