I bought tickets costing R1271

I bought tickets costing R1271.00 for Mamma Mia through Viagogo. I was seated in seats costing R350.00 each, so total of R700.00. Plus, when I presented Artscape with Etickets, there was a notice stating that tickets purchased through Viagogo were invalid. The staff at Artscape gave us a form to fill in, to claim a refund.
