Who called from 3234339434

They called my cell phone but hung up after a couple of rings. No message. I called back out of curiosity. Turned out to be a telemarketer. Message said I won a $100 credit from some website.

I'm sure this will be like many others. They call, it rings once. And they know that later when they call it will show on your cellphone "you last spoke to them" <date> and you will then answer it thinking it is someone you know. [***]!

Called, I didn't pick up, no vm.

Call my cell. For some reason it didn't even ring. They did not leave a message.
