Im not sure how i got it removed. Ive sent GW letters to every address i could find, and disputed with CRA's because it was listed as paid on one of them, transferred on another, etc. I dont remember if i paid it or not but i disputed it as inaccurate information and asked that it be deleted. I suppose if it falls off the other reports then my GW was successful.
I assumed HSBC was good with GW letters, they removed my paid HSBC BB info that was derog a few weeks ago
As for how many letters i sent, god knows, ive spent about 50 bucks in stamps the last month, id say thats worth 130 point increase lol. I do keep track of when/who i send letters to, but its at home and im leechin mcdonalds wifi at lunch right now =P
I know I sent to these two addresses:
po box 19360
portland, or 97280
po box 5253
carol stream, IL 60197
If I get home and see that i sent to more addresses I will let you know. I sent a standard GW I found here. I have a new orchard card with them, that is in good standing, that may have helped? I just double checked TrueCredit, the HSBC BB has all came off, but I payed it before it went into collection, (it did list charge/off). I cant update TC for another 7 hours to see if HSBC CC dropped off any other reports
