Has called me 6 times in three days. It is so frustrating. I have come to the point where I do not answer the phone unless I know who is calling me. If they don't leave a message, they aren't important. I just continue to ignore them. Don't know what else to do.

Has called work phone 4 times now in 2 hours and when I answer, there's no one there and then a click - and they are gone

Multiple calls a day. no messages. annoying
