Calls and hanged up after 1 ring

I didn't pick up

This number calls me frequently and never leaves a message. I called it back and it rang for a very long time before anyone finally picked up. He just answered with his name saying it's First Financial Network. No clue who they are or why they're calling!

I have had 5 phone calls in the last two days. There is no one on the line when I answer. I am getting very annoyed. Have to figure out how to block this telemarketer.

Someone called my wife's cell from this number and demanded that she "verify" her birthdate.  My wife responded by asking what company she represented.  The gal responded that she was not permitted to release that information until my wife needed to "verify" her birthdate first.  The call then ended.

This number called me alot too recently and I was put on hold then hung up on by the number while on hold...

I am being bothered by this number as well...
Did you find out who it was?

no voice message

This number calls me at least 2 times a day and there is no one there.  They do not leave a message either.  It is getting pretty annoying...

It's annoying.  I thought it was my ladies jealous ex-lover.

These a***ipes called at various mornings; no message, no response. Very weird.

This number has been calling me every now and then, nobody responded. It is anoyting.

This number has been calling me from time to time stating it is a bank and is trying to get money from me. I don't even have an account with this bank.
