These calls are very annoying!! They occur very late in evening with no left messages. UGHHHH...wish the DO NOT CALL REGISTRY worked, but it doesn't for spam dialers :(
I called the number back today since they don't seem to want to give up on ringing my phone constantly. A recorded message states that they are "Insurance Servies". If you listen to the entire recorded message, you can opt out by pressing # 2. You then get a message saying that it will take them 5 to 30 business days to be taken off of their list.
