Lately been getting these sort of calls in groups or 3 or 4 numbers...all calling and ringing the phone a couple of times...a pause, then same again from another number...all in less than a single minute.
Call in the Netherlands in November '12: Guy from 'Microsoft in India' wanted to get access to our pc and sell us a solution to our so called 'pc problems'. We hang up just in time. We were called several times again in the weeks after.
I received a call from this number (1-718-788-9020), the person sounded to be of Indian or Pakistani origin, offering some promotional package on behalf of Bell Canada. I found out that he was collecting my personal information, which I denied to provide. He already knew my name and address-I don't know how? So be careful.
This # calling me now. Did not answer, no message as usual. Just frustrating that they call to try and scam you or infect your computer. Says it was from a pay phone!
