QR CODE DOES NOT WORK!!!

QR CODE DOES NOT WORK!!! THIS IS THE SECOND TIME I AM FILLING THIS OUT!!! EVEN AFTER TESTING THE QR CODE ON THE PROOF THAT I RECEIVED & IT WORKING, WHEN I RECEIVED THE STICKERS, THE QR CODE DOES NOT WORK!!! THE ONLY REQUEST I MADE WAS THAT THE QR CODE WORKS! IT WORKED ON THE PROOF, BUT NOT ON THE STICKERS!!!
