Unfair treatment by my the MFC Nedbank

I had a bad experience with my bank,I just lost my father during good Friday weekend on the 16th April 2022 due to that I wrote an email to the bank explaining that I won't fullfill my obligation of paying the car at the end of the month due to financial constraints and funeral arrangements as I'm using my car for business purposes,So for 2 weeks I couldn't use my car on business.The requested the death certificate of my father and a motivational Letter explaining why they should extend my installment for that month.I did that and they rep**** confirming that they have received those documents and that they will inform the supervisor who will approve my request I didn't get the approval confirmation instead I have been receiving emails telling me I should pay the car or legal action will be taken against me.Even today I received messages telling me of that and also received a call.As a client I thought the bank will be sympathetic towards me as loosing someone like your parent is very painful and stressful but no they kept on reminding me that I owe them and never thought of all that I have requested.I have been paying the car without any problem from 2019 but only for 1 month my Bank which I am a client to couldn't care less about my situation they only wanted money
