I've been getting these calls for over a year! Yesterday three times, and already one this morning. I've received both Medical Compensation and Windows Technical Support calls, neither of which I fall for, trust me. My husband went as far as to tell one Easterner we ran Apple computers. I told the Medical guy this morning that I had called the FBI, and that all my calls were being monitored. He hung up, of course. One of the calls I got yesterday was from a guy with such a heavy accent I told him he wasn't speaking English. He then proceeded to spell out his most difficult words, and half of his alphabet was equally unintelligible.
I called the local FBI office this morning, and they told me that unless I have actually been scammed and lost money, they can't help. I facebooked about it, and asked everyone to call the number and harass them in return. Don't know if that will do any good.
I too have received numerous calls from this number...and others, I do not answer numbers which I do not know. If they want me to call them back they will leave a message if it's that important (these callers never leave a message). I don't care how many times they call wasting their time, I just simply don't answer and block them...and the next number they use...and the next, etc. Let them call their lil hearts out!!!
I got the same call as +972 3-480-245. Didn't answer, but looked it up, call from Israel. Gotta be scam people trying to steal Identities or get your money illegally.
