Called at 11:30 AM. Did not answer, no message left. Same number called last week. Same thing. Thanks for your input. Won't worry about it and will block.
Received call at 3:00 pm. Nobody on other end. It is my opinion that this phone number develops a list of "active" phone numbers for use by other organizations.
Got a call from this number today I answered hello 3 times and when someone asked for my husband I said "who is this I said hello 3 times" she hung up!!! I blocked the number!! :(
