I pay my Barclaycard with my Starling card every month. Start date is the end date minus 3 years.
Also Pay-at-Pump can be quite hit and miss with Starling. It is about how they take the payment, a pre-auth of 1p or something. Was massive threads on the community page before it was taken down. They insisted they were handling it the way defined by Mastercard and the merchant was not hence the issue. I have had to go to kiosk a number of times because of this but I have not tried recently just because I got used to going into the kiosk
