Don'tknow who this was

Dont know who this was. Didn't leave message and when I call back, it is always busy.

Allegedly a debt collector trying to recover a fifteen year old debt. I told him to watch his tone when he became rude, then he hung up on me.

I keep getting calls from this and other numbers around that area. They never leave a message or when I answer they do not speak. Has my a bit curious as to what is going on with them. I dont answer them anymore knowing that people can get you information now a days with a touch of a button. Figured if it was that inportant they could leave a message.
