Missed live online show due to technical errors and lack of effective support

I purchased a ticket for Moonga K's live online show on 10 September 2020. The ticket was purchased on 7 September and I received confirmation of access. At the time of the show I was directed to a webpage titled "Moonga K." with the show's reference number. However, upon clicking "Watch Now" I was greeted with a previous Africapella show. I could not see any indication of Moonga's performance. I then took to asking for assistance in the "live chat" box. The assistant, Edna, was immensely unhelpful. I was provided with information about Africapella - for which I did not ask - then was shown the date, time and cost of Moonga's show - which I already knew and purchased. I repeatedly expressed that my problem was that I was unable to view Moonga's live show. Edna responded "Moonga K's show already started at 7pm." I repeated, exasperated, that I was aware of all of this. I asked to be put in touch with someone who could effectively assist me with my problem. I was told, several long minutes later, that the query had been escalated to a supervisor and I would hear from them shortly. I waited patiently, to no avail. I was thereafter greeted with a message that said they were offline and it was after their business hours. Problem had not been resolved in time for me to properly access what I had purchased. *About 15 mins after the show I received a call from Edna, informing me that the issue had been resolved. I confirmed that I could now view a recorded version of Moonga's show - for which I was grateful - but that I was still appalled by the lack of effective communication at the time of the problem. For the apologetic phone call I have upped my rating from 1 to 2 stars. However, my issue was not resolved in time, and I didn't get to "attend" the *live* show I purchased.
