I am having "fun" with the chargers at work this morning, Shell recharge ones so you either have an RFID card which is in the post or you can scan the QR code. Yesterday parked up plugged in scanned the QR put in my payment details everything chugged along nicely.
Today parked up at another charger in the row, plugged in scanned the QR code "QR payment not available" error, tried the one next to it same error.
Drove down to the working one from yesterday got it all setup and went to my office. Popped out an hour and a half later just to check it as my MG app isn't setup yet and it was just sat on connecting so no charge. Cancelled that one, plugged into the one next to it cars pings up it's charging lovely. Put payment details in hit confirm "FRAUD" error pops up
I've walked away before I kick something

and I'll stop at a BP rapid charger on my way home and prepare the lube. Home charger can't come soon enough...
