Sorry, I don't mean to be crass, but what do you mean by 'slow pays'? You mean holding a balance for an extended period of time, or not paying the minimum payment on time?
If it is the later, then that is just kind of how credit cards work no matter who is the issuing entity. I have myself hit some rough spots and called USAA and worked it out in the end.
