Viagogo sell tickets at extremely elevated prices

Two tickets were purchased on the Viagogo website for the Federer vs Nadal charity match held at the Cape Town Stadium for a total of R10000 (Ten thousand Rand). The tickets, when delivered, were found to be valued at R1300.00 (One thousand, three hundred Rand). All done on line. Whereas Viagogo may defend the legality of their website, the ethics associated with their operation are the worst I have ever experienced. It is a ****.
