A reader asks…

I have two credit cards that I have used over 5 years ago and never paid back. The total of the two cards FIVE YEARS AGO was $1000. Of course, by now, it should be close to $3000 because of all the interests.
What does debt consolidation do? More importantly, can it REALLY remove or reduce the interest that built up over the last 5 years?
When doing a search for debt consolidation services, I get THOUSANDS of results. Which debt consolidation services are better?
Detailed answers would be appreciated.
