these calls need to be reported they are from other country's to get our information,,

today i have received 5 phone calls from an unknown caller who is calling from 3 different numbers. 322-499-4567/ 721-299-3456/ 322-399-4567. i tried calling back to see if i could get an answer and the 322 numbers say the number doesn't exist. the 721 number says my account does not authorize me to call this number. it could be an international number. i received 5 calls in 10 minutes. it is annoying and very suspicious. please investigate this so this comes to a stop. thank you

i get 3 to 5 call of this number, it piss me off ~~~~~

I was very upset due to the multiple calls for number 721-299-3456 on my cell. I answered the line there was no one there just hold music. I held and there was a man with a forgien voice that said Hello. I asked him who was this. He asked me who is this.....I began to curse. Then he cursed back......

This number shows up with "Name Unavailable"  every few weeks.  No one is on the other end and today they have called twice in 5 minutes time.  ARGH.

I keep getting calls from a 721 299 3456 number an
d no one will answer when I say hello but my wife answers and they speak to her in a foreign language and latley we also get called from and 801 805 7995 number as well as a 322 399 4567 number . who are these people

I have a hunch it is the same people just my caller ID is showing different numbers almost every time.  Again, invalid area code.  When I answered there was no response, but I could hear clicking as if someone was trying to hang up on their end.  I wonder if I should not answer?  Am I just validating my phone number for them by doing that? They don't leave any type of msg if I let voice mail get it.
