We are constantly getting calls from this phone number. Whenever someone answers the one who is calling disconnects. The calls are obviously made by an automatic dialer which uses "predictive dialing" to find the best time to call. It's irritating to say the least. I have called the number but the line is always busy.
Dont worry, they didnt target you. They'll bother you for awhile(can be a long time) then give up. I have this happen to me all the time. they usually dont last for over a month though.
