How long has it been since the charge offs and how many? I just got a 30 day late and an old charge off removed by them. Just keep sending them every month, lol maybe eventually they will if you keep sending letters. As long as they are paid I have seen them remove items via GW. Sometimes they do want them to age a little.
That is kind of soon, you could keep sending GW letters every month and see if that works. You can also go the dispute route and see if you can find anything inaccurate on the reports and hope to get them removed that way or with time constraints.
Worst case, there are credit repair companies that specialize in this kind of stuff if its something that needs to be done in a few months but they may be able to get them removed.
I don't recommend the big ones if you go that route, try to find a local one that uses an alternate name while disputing/mailing the CRA and Creditors etc and has experience in the field. The local one I used for some stubborn accounts was made up of former mortgage professionals and they helped a ton in a very short period.
