Who called from 3864922293

I recieved a call from this number, after saying hello several times JERRY
came on the line, (in very broked english) and said he was from Celect Tel,
or something like that. He said I would save 30% Next month on my phone bill and I did not have to do anything. I said OK then he wanted me to confirm my phone number. I DID NOT. I asked him a couple of questions and he hung up.

They called couple times that evening and no one was at the other end of the line.

they called me this evening while having dinner @ 7:22 pm today, pick up and hung up on me!  the caller id number came up and name is unknown!

I received a call this afternoon from a fellow informing me that starting next month my phone bill will be lower by 15%.  He needed to verify some information.  After pressing him, he admitted that he was from Select Tel and the purpose of his call was for me to switch telephone companies.  I hung up.

I have received several calls from this number and no one is on the line...
