Pathetic service from standard bank VAF division

I have been contacting the vehicle and asset department of standard bank to arrange a notice for the settlement of my vehicle and up to this date I have had no response. The call center staff don't even know about the placement of a 90 day notice to avoid paying interest. I have called today over 5 times and waited for more than 10 minutes at a time with no answer. I was once asked to write an email to vaf@standardbank which i did but still no response although my emails have been read. Standards bank service is absolutely pathetic , hence i closed all accounts with this bank and this is the last account that i want to close. i have been requesting this notice from the 18 May 2020.
