Hathway / Gujarat Telelink [GTPL] — internet package

My plan for 2 mbps internet service was of 24 months period, but the company stopped the service after 18 months only, due to some error generated in their system. Even after complaining about that in advance of approximately 10 days the service has stopped and no employee in the customer care helpline is taking it seriously. Service center in charge refuses to take the responsibility for the inconvenience. Even after waiting for a day, as per the advice of this person, i did not get the service back. And this is only one of the problems we have faced, besides this slow internet, blocked internet service for some days due to company's fault, etc diffculties i've ready come across during this time period.
