Who called from 4072050199

Keeps calling won't leave a message. When you try to callback, the message says they are on the phone. Afraid of what would happen if I answered.

The same message as above. They call here constantly and won't leave a message. Sometimes they call several times in one day and still don't leave a message. It is very annoying!

Called me just now. They didn't leave a message.

Called... I answered... asked for M...........,  I said who is calling....... then a few seconds...... click.... and the dial tone.... lol.

407 205 0199 keeps calling about 3 times per day. When I answer, there is silence on the line.
