Convergent can be easy to deal with, though only have experience with getting Tmobile accounts recalled from them for a pay in full for deletion... Friend of mine had some luck with ATT as well..
Great! I went ahead and applied for OpenSky so Im waiting on that deposit to clear. One collection was removed from my report this week so my equifax went up +15 points! Still working on getting the others removed as well. Thanks for your help!
