Indian Caller trying to claim we're owed compensation. We are not!

I got two calls from this number but the guy just hung up. on the phone it came up as +30 10

Every day, I get a call from Caller ID 3010 or 3015. How can a call with only four digits even go completely through to my phone? Obviously spoofed the number to hide the real purpose. I don't answer it. I don't answer any number I have not seen before until I can research it. DON'T YOU THINK IT IS ABOUT TIME FOR THE VERY EXPENSIVE US FEDERAL GOVERNMENT, (WHO APPARENTLY HAS UNLIMITED CAPABILITY TO TRACK AND MONITOR ALL CELL PHONE COMMUNICATION) TO PUT A STOP TO THIS CRAP?
Then there is the bogus "fund raiser" who calls from: 1-702-978-6923 (also a "spoofed number") saying they need a donation for breast cancer research. The tragedy is; it makes it difficult for legitimate charities to raise money. What kind of sick person thinks breast cancer is a tool to scam people? Breast cancer is devastating.

Got a call from +3010. Hung up when answered. Sick of this!

Just got a call from 3010.  I didnt answer, but they call at least twice a week or more!
