Is Debbie Berg and 123RemoveFast a scam? Yes it is in my opinion.
In my opinion, and personal experience, This person is not only incompetent, but a greedy money-grabber. Do not turn over power-of-attorney to her, and then allow her to charge excessive fees for trivial, poorly done services.
She charged my friend ($1200) for next to no work. She tried to charge me and hide the fact that she had already been paid by a partner service for her work. She invoiced me for 4 figures for removing inquiries and one slow 30 day late payment item. And to top that, she couldnt even remove all the inquiries, I had to pay another party after her failed efforts.
