Someone (a child's voice) called me 8x in 1 hour. First time, I told her she had the wrong number. The 2nd time I hung up. The 3rd time she yelled, "Who do you think you are hanging up on me?". I hung up again. I didn't answer the next 5 calls.
Thinking it was a child, bored on spring break, I intended to call the number this evening & speak with her parents. Unfortunately, she started calling back again tonight, 7 hours later. Google indicates that it is a cell phone.
