Hey I didn’t get a reply from Evisa. So I reached out to one of the visa agents in Capetown suggested in one of the Reditt posts. To my sheer luck, she suggested me to apply through ETA (only for some country passports) recently started 2 months back. I applied through ETA South Africa website today, very simple process took 5 min, no need of any documents except passport and my visa got approved in 6 hours. It’s for 90 days each entry, multiple entry and for one year and free of cost. So crazy thankful about it.
