ZEP Can't Schedule Appointment 7 Days After Cash Deposit

I paid for my ZEP application at Standard Bank Ellis Park (JHB) {Cash Deposit} last week on the 13th October 2017. A week later today I can not schedule an appointment. The system says :

Please wait for 3 working days to schedule the appointment after making payment at the bank. In case you are unable to schedule appointment even after 3 working days of payment, please contact VFS helpdesk **********

I have tried calling and emailing VFS more than 20 times but I get bounced from one agent to another. If I email, ********** as stated on the website, I get refereed to another email ********** an then no response.

APPLICATION REFERENCE : ZEP **********
