Who called from 2155864530

unknown, didn't answer no message

Same as above, unknown caller,didn't pick up,no message left.

This numbers calls two to three times a day never leaves a message also no one ever answers it

I answered, they said they were calling from "...associates" I can't remember. They knew my name and would only say it's a personal matter and ask if i am me, when i told them they had the wrong number, they hung up.

I keep blocking the numbers and they keep calling from the next one. They don't leave a message but it's a collections agency. Why the do call and nobody is on the other end? just to annoy people ?
