I-On — Refund for no service

My internet is down since[protected].
Since then i am trying to reach their customer care but no response yet. After 5-6 days of internet breakdown their technician called me asking about the problem. This was happening too frequently. They were not fixing the issues on time. As i work from home so internet is essential and so i decided to discontinue services from ion. I have asked for refund but they have never responded since my first email on[protected].
