Viagogo refuse to refund 5,500 for swan law tickets that actually cost 1600 - Nedbank refuses to stop card payment despite complaint

I bought 3 tickets for swan lake - the final amount was not reflected before I authorized payment - I was charged R 5,500 for tickets that cost 1600 in South Africa ! This is ridiculous, ***** and *****ing. The end cart does not properly show all charges prior to check out - the website makes you put in your card details first and then charges you and then provides an invoice - this is **************** - the worst is when I asked for a refund and cancelation they refuse and tell me to resell my tickets ... with no guarantee that I will resell the tickets. I reported the matter to Nedbank ***** division. They requested I fill out a form to report the matter - I asked them to immediately stop the payment because I know that payments only get processed within 24 hours - nedbank refused to immediately stop the payment after I had alerted them to. Thus nedbank is supporting this ***** instead of mitigating the ***** by immediately stopping the payment.

Viagogo refuses to refund me and nedbank this far has done nothing it has been 4 hours and I don’t even have a ticket from viagogo - they took my money and don’t provide the tickets I am disgusted I want my 5,500 refund - this is ********
