Calling and living No Messages

No message left. From the caller ID this looks like a legal service from South Florida, no where near where I am (Minnesota). I think this was a mis-dial as my area code is 952.

Received a call, but they left no message.

Called, did not leave a voicemail.

Number called here, id shows as "unknown", they didn't leave a message.

9546065618 Getting calls just today from this #. They do not answer when greeted and have called just 3 times in the past hour all with the same response. Often there's is a pattern of so many calls per hour since these calls have been made before. I would like to know how to end this. Looking up the number online and it says its spam from FL and a land line but you have to pay so much mouthy to get access to the complete report. Anyone know of a way to know the name and address for free? More often then not the calls end up being unknown name on the caller ID.

unkown name to me
