I received four phone calls from this number in under a minute this afternoon. This was highly inconvenient as I work the graveyard shift and the phone calls woke me up (I use the Do Not Disturb function on my phone, meaning that the first call was silent but subsequent phone calls from the same number in under three minutes will ring). None of the phone calls left a message and I was too startled and disoriented to answer the calls.
I'm inclined to return the favor by calling this person at 3am when I'm at work.
