Fnb

Fnb put a hold on my account since 4 February 2021 even after I've given them evidence that I was expecting the funds from someone who owes me there is no communication whatsoever from them infact I saw a note from the lady assisting me in branch where Mr. John Volmink told her I will never receive service from Fnb. They currently deducting service fee every month from the funds thats on hold. How do I resolve this matter.
