Terrible Service Received from Standard Bank Vehicle Asset Finance

I would like to expresses my disappointment and terrible service I have received from Standard Bank VAF (Vehicle Asset Finance) since the beginning of the National Lockdown. My car is financed with Standard Bank Vehicle Asset Finance at the month end of March 2020 my car's installment was increased by R800 and when I phoned them to find out why I was told that Standard Bank thinks that I don't have insurance for my car, I made them aware that is not the case and I thereafter sent them my proof of insurance and 2 months payment thereof however to my surprise even there after my account was still not updated. I phoned again and I was told that my insurance details were received but my account was still not updated therefore I still got charged for their Hollard Insurance again for April 2020. At the end of April I phoned again to query this and I also requested to apply for a payment holiday and I was told that should expect feedback for approval within 7-10 working days. Today it being the 27th of May 2020 I still didn't receive any feedback since from then, I phoned Standard bank VAF again today and the Consultant told me to send an email asking for feedback and that I might get feedback with 7-10 working days. How long must one wait to receive feedback? I have not missed any payment on my car but I have thus far been treated so unfairly and they've shown that they actually just don't care.
