I have been with Care One for 2 years now, and am happy to say that in 11 months I will be debt free. You need to pay attention, read your mail, and monitor your bill balances.
They negotiate better interest rates on most credit cards and loans, but you are still responsible for the bills which they were unable to help you with. Its not Care One's fault you are in debt. You are ultimately responsible for your own debt. No one would be suing you if you had made sufficient monthly payments on time. Care One doesn't remove debt, they simply try to get you better rates.
I'm currently paying an average of 6% interest on all my card debts, whereas before it was about 20%. They have saved me a ton of interest, which means that I can pay the cards down a lot sooner.
