When I first began with WT, I was concerned and skeptical. They did exactly what they said, though. My credit score came up enough to start the refinance process on my house because of divorce.
I didn't need to babysit them. Unfortunately, I was not able to complete the refinance(not their fault), and my credit declined. Now I'm trying to do another sweep, and add a tradeline or two, and I'm having a hard time getting a response.
