Called at 1:27 am but did not leave a message.

Just like many others, I received a call from this number around 2AM. The deciding kept rambling about credit cards etc. I hung up half way thru the call. I called back this morning, but the system says "this is not a working number". How do we report such scams?

Called me at 1AM on my work cell phone. Wasn't happy.

WARNING--BEWARE!! These callers are   B I G   credit card criminals, known as the card service scammers! Under NO circumstances, give these lowlifes your credit card number, or you will regret it forever!

Received their pre-recorded credit card message at 2:03 AM.  Pressed #1, as requested on the message, to talk with a rep. just so I could tell them what Ithought of calls at that hour but all it did was ring.  Tried to call the following morning but still no answers.  Just endednup blocking the number.
