Bankruptcy is an option. How much debt do you have relative to your income?
Missed credit payments hurt your score for a while (7 years iirc) but bankruptcy hits is HARD and will stay on your report for 10 years
Another option is litigation. I’m not sure if someone would take this on as a contingent fee case or not (edit: in a contingent fee, you don’t pay up front, you pay with your winnings. Very common for injury, workers comp, etc). If not, you’d need to seek out pro bono help, which is certainly available, especially if you’re in a city.
Edit: to clarify, I mean litigation against the debt consolidation company for a potential breach of contract
