Asus — Asus Zenfone 2

I am really disappointed about this, I live in Sri Lanka, and my friend in USA sent me this phone as a gift, I cant complain him that headset is missing, since its gift and not ethical, when i contact the vendor Newgg they asked me to contact the Asus, then when I contacted the Asus they tell me that they dont have any headsets to ship and asked to contact asus in India which is near Sri Lanka, Could you please look into this personally, I hope you will understand what it feels like to see the best part is missing in the phone a friend has shipped you as a gift for birthday, and the worst is that you cant tell it to your friend because it is a gift, please look into this im admirer of asus and dont let me dissppointed like this from calling around from vendor to manufacturer and then to India who keeps me diverting like this. when i called asus and told the problem she asks me where is the Sri Lanka the serial number of my zenfone 2 is the serial number F5AZFG10X794 my address is - No 42/1, Wata Mawatha, Nawinna, Maharagama, 10280, Colombo, Sri Lanka,
