Can anyone recommend a credit repair company that is legit and not a scam?

We suffered with the recession of 08'. We nearly lost our house. We have a previous bankruptcy in our history as well. It is probably discharged. But over the years since I know there are errors and other debts that have popped up that are caught in the web of resold-debt collectors and the dispute process is so entrenched and time consuming I would like to hire someone to help me through it. I see commercials for companies and have also seen some reviews on yelp but I dont want to cold call someplace without knowing about them. Who has used one of these companies before? Did it work? Was it a good or bad experience?

Really no such thing. They'll go over your credit and maybe fix something to make it right, but overall the initial damage has been done and generally speaking can not be undone by anyone including a third party that is gaslighting you into paying them good money. Been there. Done that.

Pay the debt, companies don't do much but cost a lot. It's really up to you.

I wouldn't give anyone access to my personal information or credit details. I understand how overwhelming it can seem and how easy it appears to hire someone to do it for you. I've been there. You can't undo financial choices from the past. And your money may be better spent by paying your bankruptcy attorney to deal with old debts or paying your current debt..

You can get a free credit report from the 3 credit reporting bureaus every year under federal law. (Annualcreditreport.com). Each credit reporting bureau has slightly different dispute processes for errors. A debt you agreed to pay that didn't get paid is not an error. A discharged debt that is still showing is an error. Any detail or debt that doesn't belong to you is an error.
When did you declare bankruptcy and what type of bankruptcy? This will tell you how long that will appear on your credit report. Once enough time has passed since your bankruptcy discharge, your credit will improve.
What debts were discharged in your bankruptcy declaration? Any debt discharged that was later sold can be removed from your credit report by filing a dispute. My advice is to take every debt collection call and find out every detail you can. Be honest and tell them you believe the debt was discharged in a bankruptcy. By federal law, they have to stop calling and trying to collect a discharged debt.
Cleaning up errors on your credit report will improve your credit score a little. The best way to improve your credit score is to pay debts on time and reduce how much you use credit (called your debt to income ratio).
If post bankruptcy debt is an issue, you may need to make some changes and commit to better debt management. There are often free or very inexpensive classes available at libraries or through county/state human services departments. I can personally give a thumbs up to using Dave Ramsey's debt snowball reduction method to reduce debt and gain control of my personal finances. I learned how to use this system in a free class at my library.

Good luck.
