Called my cell this am. I answered and heard 1 beep. Don't usually answer calls of numbers that I don't recognize, but I was curious. Won't make that mistake again.
216-539-0107 called me this a.m. from Ohio. I was hesitant to answer but I do business with a company in OH and didn't want to miss their call. Big mistake. It was a recording telling me that I had "won a prize" from WalMart and to press 1 for a live operator. I did that and waited a minute until the operator came on the line and said something like, "Please give us your name and address so we can tell you what prize you won!" ha ha. I told her off and hung up. Also instead of reporting these jerks to donotcall.gov, which is useless as far as I can tell, I saved the number on my phone and assigned it a special ringtone consisting of one beep so I don't have to mess with them again.
Of course, they will add my phone number to a "special" list and sell it to anyone who wants it. <sigh>
