Apple in Serbia

Can someone tell me when we can expect from Apple to be more available in Serbia? Like App Store, Apple Pay, Apple Music, TV... There is a lot of people in Serbia who use Apple products and i can’t see reason why we couldn’t listen to music on Apple Music, pay in shops with Apple Pay or have our own App Store. Even other countries with smallest population than Serbia have their own App Store (Serbia has around 7 milion people). I personally have iPhone, iPad and Apple TV. Every tehnology company that is available in Serbia like Samsung or Huawei offers its users in Serbia everything what they need. Please do something and make me not to stop using Apple products. I hope we will see changes soon.
