I've experienced great trouble from TATA mobile services. I am using the number 9268308675. They deducted some 100 rupees from my account without any prior info, and when I called the customer care, the executive talked rudely. Neither told me the reason of the deduction nor registered my complaint. And when I asked about the TATA center in my nearby area, he just cut off the call. If this would remain the autocracy of the company, how would its customer survive.
