That was the summer vacation of june 2015, i have nothing to do so purchased a sim card of tata docomo, as at that time I dont have any idea about what is network coverage, customer services and what are charges and billings.
But after purchasing that sim card how I spent my vacations, only me knows. These guys deduct money from account(sim), and when I ask them on their customer care service they said that I started some service/plan so, they deducted money, but that was wrong, i didnt done anything.these guys loot people.dont buy tata docomo.
