You know, I had a sales call come in not long ago that disguised itself with a caller ID of "Hospital"? The only thing 'off' about it was the area code. My heart was racing, thinking that someone I loved was severely ill or had been in an accident.. But that pissed me off so badly that I waited on the recorded message to end and blasted the broken English speaking human on the other end.My phone sits on my desk here at the PC if I don't know the caller, I don't answer. If I am away from the phone, I just look at it later and decide whether to return the call or not.
You can type in the number into Google and most often find out enough about the unwanted calls to know you did not miss much. LOL
(Man, did I give them an earful for about 5 seconds. They hung up on ME which made me even more mad).
I filed a complaint with the FCC. Not that it probably did any good. But by the time I was finished filling out the complaint form online, at least I was calmed down..
