Bank with inaccurate information to customer,statements differ from one another,not even having empathy to widows and consultants are always not available and offline...bad service ever

My husband passed away on the 15th of July 2020,his vehicle finance was with standard bank after his passing around August if not September I went to standard bank mall of Africa to check on car insurance as he was the 1 who was paying the car ....over the phone I was told that the car is paid up on the 4th of August 2020...and by then I was not in a good state in terms of my health....around December when I want to change ownership of the car I called another lady who was assisting me with the home loan by the name of patience she then said the car is not paid up ......then she send me to the other guy called Leigh Mark's.....irresponsible consultants ever ,I struggle to get hold of him but I end up talking to him and he send me an email showing the amount of money that was left as they saying there was no life insurance....which was R 111 701.55,I manage to pay 30 000 cash ,and after 2month I paid another 30 000 last week I've send and email to settle the now I got an email with R132 532.60 outstanding balance upon death they now differ with the first email settlement amount of R59 077.21 I really don't understand. Can a good samaritan help poor widows like me this is really un called for...
