I have been complaining more than 5 times since last 1 month. Every time i call customer executive, he or she register my complain and promise me a date. But my problem is not resolved yet. I called 5 time after every promise date but here i am with same problem. I live in ahmedabad bopal area nd this area is v crowded. I want to write more but there is a limit of 350.
