I bought wind 4 with jio sim in month of June from state of Jharkhand. Its working good but after 2 months it just got turned off. When i check with service center he demands money. I asked him for what then he told me its your internal problem but i told him its only two months then i asked him to give me a undertaking. How much charge then he refused and told me i cannot help. So please reply me what can i do. Its disaster by please guide me.
