Anyone else had this issue? I've tried 2 now including the one at T3 Delhi airport and both transaction errored. I've pre-notified Macq about the trip through the app and used in HK ATM without issue. Have also paid at a hotel with it.
My Citibank and ING debit cards work fine. Lucky I have plan B, C and D (28 deg but haven't tried in ATM yet).
Update: Macq card worked again back in HK. Beware of relying on Macq card for ATMs in less developed countries.
Just booking a flight to India now to help investigate. Give me 36 hours and I'll let you know.
