Called at work. Claimed to call back ASAP about an Urgent Matter

Constantly ringing at all hours of the day, I have never answered the calls as the number looked strange. Googling the number reveals that it is Virgin Media with some kind of marketing scam.

they call and no one responds. they have called 5 times today. interupting a call I was on that was long distance. These are a nucence and need to be stoped. I am disabled and to try to get to the phone and then no one is there. I am sirously afraid of falling because of these calls. they call about my credit card problems "which I don't have as I do not carry a balance on my account. It's got to stop before somone get hurt.

Called after 10 PM! No one there when I answered.

Caller with a heavy Indian accent called my work phone stating he was "Derrick Smith". He said that the second I receive this call, either my attorney or I need to call him immediately. He also tried using scare tactics, saying that I should not disregard the message and if I did, "good luck". He ended the call by saying "God Bless You".
