Spidigo — no service and not receiving my calls

Address:

Spidigo broadband pvt. Ltd. Claims to be a internet service provider but they are nothing more than greedy scammers.
My spidigo connection had not been working since like 3 months from now expcept one or two rare occasional days.
I had written emails, called like a hundred times still no solution. Initially at least they used to register the complaint but now they don't even pick up their consumer care helpline, whenever you call its busy and then the call automatically gets ended. The engineers who provide service are extremely rude and give false assurance and after a point of time start ignoring the calls. Even before these 3 months of complete internet shutdown they had an internet problem every week and the speed was not even close to what was guranteed by the plan provider. I demand my annual subscription fee back as refund and an apology from spidigo for such bad service.
