Money management org? Should I do it?

Hey PF, essentially my debts has spiraled out of control for my CC debts and I wanted to lower my APR so I called one of my creditors (Chase) and they led me to moneymanagement org to essentially pay off my debts as best as I can with a lower APR, but it would close my cards that I enroll with the program. Wanted to ask if anyone has any experience with them and anything I should know if I move forward with the program?
