Yo Mikey, you know I got your back.
But honestly this seems like a pretty typical thing in the process of issuing credit. You're young, coming up fast. You know how to hustle and get what you want. When you talk to these people, they're going to begin filing whatever paperwork they can to get you going. Even if it has to come down from the top that they can't do it, that might take a bit of time. She might have even tried to go to bat for you on the issue only to be denied from management. (I worked at a car dealership for a minute way back, it happens a lot on credit issues or did 10 years ago anyway.)
Also, just to face facts, I had this happen to me over a much larger issue I've tried to face and address but circumstances have prolonged the issue. This sort of thing can keep someone from getting a job for quite a long time. Even if she is completely inept, people are still people; we all fuck up, or have fucked up. That doesn't mean we should be denied future chances at doing things right by learning from our mistakes.
Not to mention, going after her personally versus the company seems a bit harsh. Typically a company has liability against the actions of individual employees, but with the transparency of the internet I don't think employees get the same respect.
What happens when her friends search for her name out of curiosity or for some viral facebook post?
Anyway, just some thoughts from a crunk affiliate. Handle your biz son.
