Technically made off without paying once. Went in to pay, gave pump number and paid what seemed a little higher than expected. Checked pump as I went back to bike and realised they’d overcharged me by about £3. Went back inside thinking this will be quick to sort. 15 minutes later it’s finally sorted; turns out I’d paid for the guy on the bike at the pump behind me. About 6 weeks later I’m at another Co-Op petrol station about 40 miles away. Try to fill up but can’t, and they ask me to come inside where they mention an unpaid transaction. Clearly they’d refunded me, charged the other guy the amount he owed and didn’t actually process the transaction at the pump I was at. Anyway, I was able to show them the amount owed via my banking app by way of the amount paid on that date minus the refund which was, of course the amount owed. They said they’d make some calls to sort it. What surprised me was the fact that they had erroneously had me down as not paying, but done nothing about it until I’d returned to another one of their stores. Avoided the stores for a while until case it still hadn’t been sorted. Eventually did use them again, no problem. Pleased they’d finally sorted it, until about ten minutes later realised it was probably because I’d part exchanged my old bike. So if you bought my old Z1000, sorry if the Co-Op refused to serve you too.
