Who called from 3073756838

A credit card debt relief service.
A - I don't need the service
B- They called my cell phone with a recorded message - against the law.
C- I am on a the national "Do not call" list.

How do we stop  these people from calling?

I keep receiving calls from thi phone # and they never leave a message; they call every single day, at any time during day or night, it's really annoying me!!!!

We get calls from this number several times a day and they don't leave a message. We are also on the Do Not Call list.

I have the same issue. Please disconnect this number. It's ridiculous that we keep getting harrassed. How do they get our numbers?

Another nasty, criminal telemarketer, deliberately paying no heed to thé Do Not Call register. And because we use VoIP and travel, we got their cal at 1:00 am.

It's telephone spam, even caller ID isn't a solution except to the degree that merely answering tells them that the line is a working number that they can profitably sell on to other spammers.
