I have sent out some PFD letters. I have heard back from three. One from Cap 1 and of course it was a no go, and also 2 medical collections again a no go, but they did validate. I have a couple other medical and one for an old cable bill. It has been 30 days and still no word. How long do I wait before I send out validation letter? Or is that a good idea? Maybe I should say what do I do now if they have responded?
