Standard Bank poor service and bad business

I am in disbelief and I'm sure the bank is not treating me well as I have bond and vehicle accounts with them because they fail to give me actual settlement amount on my vehicle but instead gave the remainder of the payment remaining term which is dishonest in my view and I need this information asap secondly on the 17/09/2021 I called and spoke to Isaac to enquire about 70k deposit on 15/09/2021 followed by 80k on the 16/09/2021, he said both of the payments were not reflecting on their system and promised to give it another 2 days then will call me back which never happened, on 28/09/2021 I called again and I'm told to email proof of payment which I did but still nothing from them, I don't know why it seems like they are not keen to offer me a good and honest answer I transfered from my app to them with details he verified as correct on both instances. Lastly I also paid 350k to my bond account on the 10/09 /2021 through lawyers and I am very worried that the same might happen there, all I want is this bank to appreciate my efforts to do thing on my debts and I expect the same from them
