*******ed unprofessional colleagues

Got a call from Nkululeko Vilakazi if I still remember the surname correctly he said he is calling from ADA which is in corporation with NCR he said. So to keep a long story short,due to me refusing to give out my FNB account number,he got one of his colleagues who I think goes by the name of Lindokuhle who then insulted me and told me that I have debts and that he is sending people to come reposes my things that he spent even mention what they are. They are so unprofessional and I still don't know what they do or even what needs to be reposed
