No Assistance from accounts department @ City of Cape Town

My father-in law past a way on 06.08.2021 and I took over his municipality account. I sent all relevant docs to accounts & ebill. And still I am penalizing for returned debit orders. I am also a widow with only my income and struggle as it is at the moment and even the Attorney of Authority's details was forward to them. No one seems eager to assist me. This is so sad that a paying customer does not get any help from that department. I cannot get a bank statement from ABSA where this debit order is active, but still they keep on penalizing me with almost R1000 per month. I am fed-up!!!
