Can't solve their own mistakes

I am very upset with the most useless companies MBD and Norton Lambrianos Attorneys. Both of these companies are debiting separately for my absa debt. They have internal issues which they are failing to solve yet both are supposedly law companies. I want to know which company must debit from me? I'm also going to contact the NCR to try and solve this because one of the two companies have *****ulently collected my debt and I want my refund!
