We had a problem with our Nationwide Flex card being swallowed by an AkBank ATM in Fethiye a few years ago.
Got in touch with Nationwide and cancelled the card. "No problem." said Nationwide, "We'll get a new one in the post to you within 24 hours".
3 weeks later we hadn't got the replacement card. "No problem." said Nationwide, "We'll get a new one in the post to you within 24 hours".
3 weeks later we hadn't got the replacement replacement card. Called Nationwide again. "Sorry we don't post cards to Turkey."
"So, Why have I been told twice that you'd post a replacement card to us ?" "A clerical error." Was the reply.
Now, Nationwide had been quite happy to accept our Turkish address and had been sending monthly statements to us there for at least 2 years before the problem occurred, but they wouldn't post a new card to us.
I eventually solved the problem by changing our address to my parent's, having the card posted to them, and then they posted the card to us. It took just short of 3 months to get a replacement card. Fortunately we had other means of obtaining our money.
Good luck.
PS We got the original card back from AkBank 2 days after it had been retained, but it was useless by then.
