Why would Lexington Law rush to clean up your credit quickly and miss out on receiving that payment from you each month? Does it make sense? Of course not. Their business model is designed to have you pay them every single month for 12 - 24 months. There is no motivation to repair your credit fast.
Does any credit repair company you've seen on Craigslist:
1. Show proof they can get you a FDCPA settlement check like the one you see in this ad?
2. Review the collection letters you receive in the mail for violations that could make $$$ for you?
