Chancers

I am being harassed by Nimble Group for over an alleged debt with SARS for over a year now. No matter how many conversations, calls and messages later, one gets no where with their consultants and to get hold of anyone on the phone is impossible. I have followed up with SARS and have no liability with them. I resigned as a director of the company in question in 2015. I am being sent final demands for debts that don't exist. This is utterly frustrating and infuriating. How does one make this stop!!!!!
