They said that they were calling regarding duct cleaning services and i knew that it was a scam!! Right after that--they called again ani came up as unknown nam and number.

This is seriously annoying, today I got a call from +40555600842 on my cell phone at 11:09, I was asleep, luckily with my ringer on very low, obviously I didn't wake up to answer it, at 11:10 and 11:11 I got calls from a private caller, then an unknown number at 11:12, at 11:14, our friend at (416) 646-3601 called, and then at 11:15, a caller from 662-505-2872, I finally woke up at 11:18 when another private caller called. At that time I looked at my phone and saw all the missed calls, no messages though. How do these people manage to find my phone number, and why do they feel that calling 7 times in 7 minutes is going to get a response?
I tried to trace the numbers, the unknowns and privates didn't work out, but the first call was from a caller calling through Romtelecom in Romania, but calling through the provider from outside of the country. I literally don't know any person or have any connection to anything remotely Romanian. The area is Caras-Severin, which includes Transylvania. Perhaps it's Dracula.
The next number that came up, the 662 number originated from Mississipi or Memphis, Tennessee. I'm a Tennessee Titans fan, but otherwise I have no link to either of these places either.
Finally, of course our favourite caller, the one at 646-3601, called in between.

Has anyone received a REAL phone call from any of these numbers?

I was called by this terrible number many times. What a hell. How can we forbiden the number?

I just got a call from this number and the person was like "HELLO, do you speak Chinese?", no joke.

Needless to say I hung up.

I tried calling it back and it was a dial tone, as though the # didn't exist!

Call me and abused

Got a call today.  I didn't pick up, and they didn't leave a message.  I called it back, but got a loud buzzing sound (i.e. it didn't ring).
