Refilling gas (for cooking) in Turkey with Greece style fittings

[Chaff]

Hi everyone,
I have really been struggling to find anyone in Turkey (Datca Eastwards so far) that will fill or swap our little 3.6-4.1kg gas bottles. Unlike Greece where loads of random places like pet shops and hardware stores will do them I haven't seen anywhere in Turkey that seem to have the same fittings and when I show photos I don't get a positive response.
Am I missing something?
Thanks
Al
