Standard Bank sort out the your Vehicle and Asset Finance

We been trying to settle our car balance with Standard Bank for the last few days. We call and they sent us the final balance to settle the car with Vehicle and Asset Finance. When we do te payment the money keep on bouncing back into our account. One of two things I can assume is that Standard dont want us to settle our amoin tor they just not keen on us settling it because they losing a paying client. No one could help us, we been calling since the morning for assistance and no one can help us. We used the account they gave us and still nothing. So if you see this message sort this **** out STANDARD BANK. it's frustrating to deal with this. Why do you give us an account that don't work. You know it don't work. Stop this BS and allow us to settle this account.
