I've used Care One Credit and it's been a Godsend for us. They are able to reduce your interest rates quite a bit depending on the company and get a reduced payment amount. Overall you can get a manageable payment and pay off these debts much faster.
We used one years ago and it was a nightmare so definitely find someone reputable.
Some people complain about CareOne because they don't listen to what they need to do upfront. The first month can be hard because you need to make a payment on your bills as well as the "new" overall payment to CareOne. After that, you're good to go. The reason for this - it's take about a month to get all the processing done. If you time it right, though, you might not have to do this step. You also need to call our creditors and have the due date changed a few days passed the CareOne payment that goes out. This also gets people in trouble causing late fees.
If you want to contact me off list, feel free. I've been working with CareOne for about 3 years and they've been great.
