Standard bank VAF - refusal to make payment arrangements

I am really appalled by the way Standard bank is treating me. I am behind on my vehicle and asset account due to being unemployed for 2 months. Standard bank has instructed an external company to repossess my vehicle immediately, i offered to pay 60% of the money today and settle the balance on the 25th when I get paid. A very rude man with the name Simphiwe Dlamini refuses for me to make that payment and says that all he has been instructed to do is to collect my car and also asking me belittling questions about why I purchased a car if I cannot afford it. He left me in tears and wasn't bothered what I had to say. I have been trying to contact the standard bank call centre, but each time I hold over 45min because of high call volumes and cannot speak to a consultant. The service I have received is beyond pathetic.
