Worst service I have ever seen. Worst customer service, they dont send bills properly disconnect line without informing and have only one office when u need to go and stand in queue to pay bill. When other providers give online payment methos these guys of the 70 still believe in queues.
I requested for a new conection it took 3 weeks to get the line up and running. Then it happened suddenly when the line got disconnected when contacted they said bill will not be send by post but will be sent by email and without informing they cut the line.
Made several queries but no reply. My system got formatted and contacted the customer support on how to install and she dosent know how to guide.
As a whole dont go for this product. This is my second bad experience in a tata product an now I have decided not to go with any of tata products.
