Standard bank Vehicle finance dep has bad service.

So I stayed off work to visit a Standard bank branch today. Stayed 4 hours in that branch on the telephone with various departments but still my matter is not resolved. I was financed by Standard bank for a vehicle loan and unfortunately my car was in an accident and written off. The insurance company (KingPrice) paid the settlement amount to standard bank and even sent me proof of payment last week. On Saturday my account was still debited an amount of R5730 for a car that's been paid up. Gave them a call and was told I need to visit a branch, today I did that. Spoke to a consultant that put me through to the VAF department, told my story again and was put through to insurance and claims department. Again I told my story and was told I need to speak to the VAF (vehicle and asset finance) guys so again I was put through to a department I had just spoken to. Again the VAF guys told me I need to speak to the Insurance and claims department as my account/debt is not showing on their side. I repeated this process for about 5 times going back and forth with Vehicle finance department and Insurance & claims department. Seemingly nobody knows how to handle my matter. I eventually gave up in hopes that I will make time to visit a branch again. Mind you I'm going back and forth with these people with security checks with each and every department and the long call waiting periods. This is such an inconvenience. I have things to do with my money but now I can't because Standard bank took it. I have work to do but now I should take days off to visit Standard Bank branches. Worse part is that I can't even reverse this debit order because the very same people who took my money will list me as a defaulter or even have me blacklisted and may ruin my credit record. I've been with Standard bank for some time now and I've been happy all along but after today I'm not too sure if I can still confidently refer people to Standard bank. I need my money back.
