Same here. Calls often, but no one ever there. When call back it says "Thank you for your call, sorry we missed you." and ends with the message to try back later. When we answer the phone no one is ever there. They have called as often as 5 times a day. Usually says "private caller."
Has called my house multiple times in the last two days. Keeps coming up private caller then leaves no message when the machine picks up. Had to block the number because they just don't give up
