I can't buy apex coins in steam version of apex legends. apex coin page says" unavailable" for most steam users. I am from Turkey. 

I also have EA play subscription in steam and all EA games have 10% discount but legend packs have no discount.

I want to buy apex coins but I can't buy.

I want to buy newest legend pack but there is no 10% discount so I don't buy.

can you please fix it. 

thanks.
