ZEP Online application issue

I never experienced such terrible application and the customer service in my life! In context: I app**** online on behalf of my friend in VFS web site for the ZEP. I filled all the required information and did online payment through debit card successfully; however not able to schedule an appointment.

I have been trying from last 10 days and there is no luck. Every-time, it asked me to fill the form again and again. When I click on schedule payment, the same screen is being displayed.

For the assistance I did call VFS customer service and as per their advice I wrote the issue in detail to ********** with all the relevant screen shots. The worst part is without understanding the issue, every time I got a replay like "Try with different browser/device" , "Try after some time" . It's almost 10 days and I really helpless and don't know what to do as I already paid R1110. Is anybody there to help in this situation?
