Spidigo — internet not working for 7 months now.

Address:

17, vraj homes, shela tal sanand, Ahmedabad, Gujarat, 380058

My internet is not working since last 7 months now.
I have made numerous calls and sent many emails but no resolution yet.
Not sure what to do now. I can't find any address to go and talk their manager or any representatives.
I want my money back don't want to use their internet any more but not sure where to go. Last month pace internet support guy did pick up my call but they would either disconnect in between or will say case is created and no one will respond after that.
And its not like sometimes it works and sometime it doesnot. Its not working at all i have not used even 1kb of data.
