Free parking QR code on till slip not readable

<p>This past Sat morning I was shopping at Cresta Shopping Centre. When it came to paying for parking, I tried to scan the QR code on my P n P till slip to get free parking, but the code wouldn't scan. There was an attendant there, and he showed me that the code on the actual ticket scanned fine. You could see that the QR code on the till slip had been badly printed. The attendant told me that P n P had been made aware of this repeatedly, but have done nothing about it.</p>
