SAMSUNG SERVICE CENTER - Almaty, Казахстан

I have my old Samsung Galaxy J1 which I am using because iphone dropped and broke. It was working fine until now. Battery % goes down very fast, and when I charge it, the phone is very hot! Also no calls or messages getting through since yesterday! Help??!!

Right now im in kyzylorda. I would like to inquire if you have available battery for samsung galaxy note 8. Is it possible to send my tab in your service center by train? how much does it cost? Thanks.
