In your case, the station-specific refund location is correct. This is due to the type of refund issued to you from the Analytics team.
This is the last type of refund where it is station-specific and the Payments Technology team are working on moving this refund type to the “all-stations” solution in line with the other type of refunds.
A friend of mine also received one of these emails after travelling on the Goblin. It would be better if some way could be found to replace ‘operational issue’ in specific cases like the free travel on Goblin services in September.
He can also confirm that the station is specific as he used a different local station initially, but only got the refund the next day at the specified station.
