I finally got a PIF letter from Sureadvance. It took 2 faxes and 4 emails, but they finally sent it.
Please, anyone reading this thread, work with the information that the moderators provide, it's invaluable! It takes time, and some energy, but you can crawl out of the vicious circle of these PDL'S!
Special thanks to Shazzers, I couldn't have done it without all your time and effort. Just a couple more to go, and I should finally be free!
