YOU Broadband INDIA Internet is not working and customer care is not working on my request

I have You broadband connection in Baner Pune. My contact number is 9579565424. From last 7 months, I am facing the same Internet failure issue in every two month and customer service people are not at all helpful. They are mentally harassing us and eating our money. So I want my money back now. I am done with this stupid company and unable to work.
