Just got a call from this number. They have never called before. Caller ID said "TRAVL HELP SOS". I have no idea what that is. I didn't answer since I was busy and I didn't recognize the number. They didn't leave a message. We are on the do not call list, so we shouldn't be getting these types of calls. If they call again, I will be reporting them.
Received a call from this number a few days ago, however, I did not answer due to not recognizing the number. They left no voice mail and haven't called since.
I too am on the Do Not Call Registry, but as long as they leave no message, there's nothing that can be done about it.
