I need help

I have a bad experience with these people. I was not working for some time and I got blacklisted listed and I signed up with them. And I noticed that the process is to long. I then paid straight to the company I was owing. With the job I had , I ddnt earn so much so I focused on one company that was lewis furniture store. I was also owing Edgar's and old mutual. Recently I managed to pay the Lewis furniture store completely and the National debt advisors did help me on how I pay it. Now I want to pay Edgar's its a different story they can't help me, they giving many number to call and emails. I went to Edgar's store seeking for help as how do I pay my account. They can't see my account from their system. They tried by all means but no success. They also gave me many contacts to use. I did call all the numbers they can't help me. They will keep giving numbers again to call. At the moment I dng know what to do my life is a mess. I need help. I need my name to be cleared. I can't even apply for anything my credit score is bad. I need help please.
