YEAH!! Got the Call Today!!

Okay, so today I called the deputy who was in charge of my background investigation.
I told him that I was calling about my rejection letter and that I was wanting to find out what went wrong so I could make improvements because I was reapplying for the position.
He kind of went silent then told me he's never had anyone call before wanting to know the reason why they were turned down after the b/g check. And said that he's not the one who makes the decision just passes the info upstairs.
He then went silent again and I repeated that I would like to know so I could improve on whatever it was because I'm reapplying for the position.

He told me to call him back on Friday....so hopefully he can get some info for me.
