Disgusted by bad service and excessive charges

I am disgusted by Standard Bank Car Finance. I asked for the 3 months payment relief due to Covid, and they only gave me two months relief, but have worked the new repayments out based on 3 months relief. They have added 3 months onto the end of the contract plus worked out a higher installment, which in effect adds up to another R4000 (total ripoff) plus the extra payment of R3800 which they didn't relieve me of, adding up to R7800 more! So to get a 3 month covid relief break, i end up paying R7800 more for this finance due to their incompetence, not to mention that the extra on the repayment is a total and utter ripoff. This is totally unacceptable and will never do business with them again!
