Failing to use ticket

I purchased an online ticket for Andy Narell concert taking place today at the Pretoria Botanical Gardens. The money was deducted from my bank account but the ticket was never issued. I tried calling the number on the website but couldn't get through. I then decided to a whatsapp message and e-mail. A lady called Bongiwe responded via e-mail & requested for proof of payment etc,etc. She then later called & promised to send me confirmation and ticket via e-mail & that didn't happen. I then sent two follow-up e-mails 3hrs later. Her response was that their IT dept would send me the ticket & that also hasn't happened nor hard they refunded me. I urge plp not to use Computicket online system. The customer service leaves much to be desired.
