firm, probably vodafone on my voda fone, gave me a free loyalty benefit, I clicked ok and after a short while, a digital e card for tesco appeared worth 1.50. As I was not in tescos, when doing this, I saved the card to my phone screen so I could spend it in tescos. Next day I opened the saved barcode, and it asked me for the access code, no idea, a few trials but ultimately I could not get in. I dont remember creating a pass to get into the barcode, as i just saved it when it appeared on the screen. If it had come by email, i could retrace the email, but as it just flashes fromgift card sstem by phone the app, with no clue as to my pass code, its wasted.
