My phone received twice from this number 6235879988 which I am not having anything to do with.  And what is more annoying is it called on my new phone line, which I just got from a week ago.  I didn't have any call forward info from the old line that I discontinued.  How these scumback got my new number and what the hack these scam artist doing.  Anyone know to what authority we could report this to?

Service provider should disconnect the account 623-587-9988 as it is a scam.

This number has called me one my new cell phone at least 4 times. I didn't answer the first three, but i get fed up when they kept calling so I answered the fourth one. It was just dead silence so I hung up.

623-587-9988 just called me.

Isn't caller ID spoofing wonderful?

I think "they" are mapping out ranges of cell phone numbers.  If you answer (or voicemail does), they know it's a valid number.  THEN they can add the number to the list so they can proceed to send the SMS spam.  I'm bracing for the avalanche...

I got a call on my cell phone from that number just at 2:07 pm central today Fri July 18.  I use T-Mobile and I live in Naperville, IL.  I called back to find out who this is and received the message that the number has been disconnected.
