Bad! Please refund us our money!!

We bought 2 fast track cable car tickets for Tafelberg cablecars through Viator. We received our tickets at 1am the morning of our booking at 10am. When requesting more information we were told "you should have already been there". This was 7:58!am. We went to the cablecars through the fast track gate only to be told the tickets bought at R1000 each (which is the price for a fast track ticket) was not fast track tickets so we need to go either wait in the 3hour queue or upgrade the tickets to fast track at the offices on site. We got to the office only to be told they cannot upgrade the one ticket since it was scanned. We upgraded the one ticket at a cost of R650 extra to the R1000paid for it and had to buy another new ticket at the R1000 fast track price. In essence, a R2000 experience ended up costing us R4750. Do NOT BOOK through this platform. Communication is poor!
