Selected the location using the code, but the code did not exist in the app. Therefore it defaulted to the next location, which also happened to be a Morrisons.
I got a ticket.
I called and they fully accepted that the technical fault was theirs, but that I should have left so I have to pay the fine.
I argued I had paid, so clearly the misunderstanding was theirs. They said it was, but I should have left so the ticket stands.
I’d also like to point out the customer service advisor only gave me his name after several requests.
