GoAir — regarding the response from go air

Hello
I'm very disturbed and not at all satisfied with the services of go air
I have booked my two way flight from new delhi lo hyderabad and from hyderabad to delhi which was on 29th january and 3rd february respectively..
And on 28th i have got a text that my flight on 3rd feb has been cancelled..
Since that day i have been trying to contact your so called customer care and there is no response
And i got to know after 3 days that you the so called classy go airlines will pick the call only only after 15 min (Toll free)
And i have tried calling your customer care on 1st feb again
Finally, god's grace
Your people picked my call and after some time don't know where it went wrong, and you have cut my call again!! Like how is it even fair on your part to do this?? And after that i have been trying to contact but no chance..
This is how you treat your customer??
I want to file a suit legally if this is way you respond to a customer...
