Took my money without the ability to book appointment

SOUTH AFRICA - I submitted an online application on 12 March and paid. On the same day I tried to make an online booking however there was a message that "the site is currently under maintenance". I've since sent no less than 6 emails AND submitted feedback online, as directed by them, to no avail. I've asked to be assisted with a booking via email. I've asked to be refunded so that I may submit my application through CAPAGO. I phoned their contact number 4x yesterday and if I don't get cut-off by an agent, the voice prompts lead me nowhere. What is going on at VFS Global? You are taking our money without rendering a service!
