WHAT HAS HAPPENED TO COMPUTICKET BOOKING SYSTEM!! NOT USER FRIENDLY

I bought 3 x tickets to concert in City Hall CPT for Sun 27 April, paid, screenshot a "Purchase Successful", but have never received any confirmation from Computicket. I used to book a lot of tickets through them. Had to Login, good seating maps, now I am afraid the website is NOT user friendly, Seating map pathetic and their WhatsApp chat is AI babble, that I do not trust. How do I get confirmation of the tickets I paid for? HELP PLEASE.
