Poor service,and Unproffessional

I called standard bank to ask them to reduce my vehicle contract term from 72 months to 60 months and it's been a nightmare. I honestly dont know what they do no understand by that instead they loaded a payment holiday which comes with a longer term and ridiculous interest. I have been asking them to remove the holiday and calculate a shorter contract but still, I am given unnecessary run arounds. I have lost so much money making calls to the call center and still not getting anywhere. Can someone recalculate my contract term to 60 months and remove the payment holiday as its extending the payment term and increasing the interest on the loan. This has been going on for so long and I am tired honestly.Standard Bank: Service request no. *** , I feel like I am wasting time making calls as no one seems to understand but confuse the whole request. I only asked for my payment term to be reduced from 72 months and make it 60 months, not a payment holiday please
