Number called me as well and didn't leave a message. With my reverse call app I found that it is linked to a Keysha Nanger who is also linked to about 8 other numbers.
Thank you! Very suspicious! This just called me. I answered. It was automated and they asked if Sara was there. I replied with "Yes, this is her." And the automated made a bloop noise and said "okay, thank you. there is no message, we will try our call again later." And it hung up....
Just got a call that said "Hello, is John there?" When I asked who was calling, they repeated the same exact question. It was a recording, not an actual person.
