African bank

This bank is probably one of the worst. How does anyone allow them to get away with what they do and how they treat people. Its sad to think they are oblivious to the fact thatt there is a pandemic and that some of us barely make ends meet because we sit with 1 salary not 2 anymore due to retrenchment. Food is up fuel is up i have a child to raise rent to pay etc. I have asked them countless occassions how debt outstanding can triple from the initial loan amount. They do not give me what i ask for. I need to hold this bank accountable for the suffering i am put through. Then they pitch up at my work without appointment etc embarrasing me. My debt must be writen off. How does one sue a bank for emotional damage suffered.
