Wesbank please settle my account ***

I'm so hurt and disappointed by the way wesbank is treating me. My car was financed by wesbank in 2017. On the 3rd of July 2020. I was involved in an accident and my car was written off. My insurance paid the amount that they where suppose to pay. And the was a shortfall of R8000. That was suppose to be paid by the bank since I took the shortfall cover with them. It took wesbank 3months to pay that money. I had to fight with them before they pay the money. Shortfall was paid on the 6th of October 2020. I called wesbank on the 19th of October to find out why is my car not settled they told me there is outstanding of R4000. 00 that I need to pay. I asked the lady why must I pay that money because I received the email stating that the shortfall has being paid. Her response was that my account is in arrears credit act says that I was suppose to pay while I'm waiting for them to pay for the shortfall. I am so hurt because it is not my fault that they took 3months to pay for my shortfall. After they have being taking my money for 3 years claiming that is for a shortfall. When it is their turn to deliver their come up with stories. Why must I be punished for doing something right. Why must I pay the R4000. 00 I have being without a car for 3months. My policy could have being cancelled and settled long time ago. I work for this money. Wesbank keeps on demanding money as if I grow money from the tree. I want to get over this car thing. Can Please wesbank setlle my account. I don't get any communication from anyone from wesbank. No calls no emails. Unless if I'm doing a follow up. WESBANK PLEASE SETTLE MY ACCOUNT PLEASE
