Trouble with a Nat West account...
If I try to use the card, or the phone via Googlepay, at a certain cafe, it has always been declined. Likewise, on the local bus it gets declined, but another bank car or Gpay work fine.
Ringing NW, they have a record of the declines on the bus, and claim it was due to the card being pin locked, but they have no record of the cafe's system declining the card - odd because I pop in there and have done for years, and it has always been declined. The owners claim that they don't have any other Nat West cards declined.
Where the card or Gpay works, it completely works reliably.
