Ok, just confirmed what I said to you before - you shouldn't be allowed out on your own!
Never tried since the advent of banking apps, but years ago I recall getting a balance from a Finans ATM with an RBS card - only reason I remember is because even with money in the account, it wouldn't let me withdraw anything. I didn't have my Finans ATM card and knew there was no cash at home so ended up having to walk from Taksim to Ortakoy, at three in the morning, in the peeing rain. Mind you, given the amount of raki consumed that night I might be wrong
I tried a few others, but Finans is the only one I remember getting a balance from. The rest just told me to sod off.
Instead of hanging about waiting for someone on here, why don't you just try a few - there's no shortage of ATM's in Fethiye.
