Apparently whoever is calling has targeted me and all these previous users in a matter of a few hours. They called and only rang about 3 times and they themselves cancelled the call before I could answer. Called back 3 times and they would automatically cancel my call. On the 4th and 5th try I called back, I started getting the "goodbye" automated message.
Received the call from a foreign accented woman. She said my first name. I told her she must have the wrong number and asked what number she was trying to reach. She immediately hung up without any response.
