Admyt QR Code not freely available and NOT working in Rosebank Mall

Last week I visited the Rosebank Mall and should he qualified for the 90 free parking from Checkers. I has charged by Admyt, but then refunded when I logged a quiry. I was in Checkers Rosebank Mall again today for under 1 hour. Checkers has NO QR code that I could scan for my parking. I was sent to the Info Desk and scanned a code there. It said on the app that the boom would open which it did, BUT I was again charged R10! If this continues, I am going to deactivate the Admyt. It is MUCH simpler to collect and validate a ticket.
