Who called from 9374121187

They called during the day but did not leave a message. When I called the number back, a recording said "You have reached a non-working number".

Some random woman who could hardly speak english giving me a spiel about a free vacation. i hung up on her.

Someone with a heavy accent called saying I had "filled out a form a long time ago and won a coupon".  I hung up before he could go into detail.

A guy with a very heavy accent and a bad connection. He went into some sales pitch but I didn't understand him and hung up.

Called at lunch time, didn't answer.  No message left.
