unlocked iphone replaced with a locked one
Last year in October I bought an unlocked iphone 5s in Thailand, I live in Croatia and had some issues with the screen and yesterday apple gave me a new replacement iphone, and the replacement iphone is locked. Been talking with Apple support yesterday for over an hour, and they suspect its locked to US AT&T (but not 100 % sure if its AT&T), they can see the store info where I bought it in Thailand but they say they can't do anything to unlock it, so they gave me phone number of AT&T and said they would unlock it wihout problem.
Anyway then I started talking to AT&T support then and been talking to a couple of managers for over 2 hours, they just keep passing me to another higher level person and in the end they said they couldn't do anything, their best suggestion was that I go from Croatia to the store in Thailand where I bought to iphone so they unlock it.
I did a online check of my Iphone over IME numberI and this is the info I got:

Please help, what should I do?
