This number calls at least once a day. When answered they ask for me and if the person answering the phone says im not available they hang up. They have hung up on people answering my phone when asked who they are. Today they called asking for me i told them it was me. I was replied with "thank you" and they hung up on me. When i attempted to call them back it was busy. Then I tried again and they answered the phone "hello" I asked what company they are with and they hung up without answering me.
