Good luck with your GW campaign! I'm preparing to start my 4th campaign since beginning my rebuild early last year and while I, too, haven't had much success, I was able to remove 4 collections from my file early on. I plan on taking a similar approach as you did in the past and combine a mixture of emails and typed letters to multiple addresses to see if any make it through the "firewall" LOL. Wishing you the best!
I am with you as well. I have 2 baddies left paid collections that I settled late last year. I had hoped that since they were with the same CA it would be easy.....no such luck, I e-mailed the entire executive board and they didn't even respond. I called several times and got the same answers you got. We have to remember that it only takes one yes in the midst of all these nos, just need the right person to respond.
