O2 Priority Greggs Coffee offer recorded as used when I didn't use it

[Priority29]

I went into a Greggs hoping to use my free hot drink offer.  When I asked for my coffee and presented my O2 Priority QR Code to the lady behind the counter she said their scanner wasn't working so I couldn't use the offer.  However, in my O2 Priority app, it is saying 'Voucher used'.  I am not happy about this as I didn't use it.  How can I get this re-instated?

We’re just customers like you but it sounds like you’ll need someone to access your account which can’t be done from here. If you message O2 using the links below, they should be able to help you with this

Sounds like a Greg's problem rather than O2

Have a word with their customer services. You might get a couple of complementary vouchers

Greggs customer services are usually really good, and last time it happen at a store near work, about 20 of us got £7 worth of vouchers each, no guarantee, but worth an ask.. 

o2 wont reinstate code, as it will have timed out..
