Go Air — Refund not Initiated

I have booked my flight from Chandigarh to Delhi and Delhi to Hyderabad as your organization dont have direct flights from Chandigarh to Hyderabad.
So I booked a Chandigarh to Delhi and Delhi to Hyderabad as i have an urgent conference meeting at hyderabad.

But unfortunately your Organization has cancelled the G8104 flight on the same day when i was waiting for the boarding .Due to an urgent conference meeting I have to take a flight on urgent basis from INDIGO Airways on higher charges from Chandigarh to Jaipur and Jaipur to Hyderabad (Connective Flight). So i have to cancel the Delhi to Hyderabad flight i.e G8 423, just becoz of your poor service.
I have waited for five months but still my refund was not credited in my account.
I want my complete refund for my both flights (G8 104 and G8 423).
If within the next 7 days my refund would not be credited in my account then I will have no option except to go by legal way.
