If any one of the systems in teh line of cable has a virus the connector closes all connections in line. then we will have to wait for eternity for the guys to come and clean up the mess and restart. If you have paid the recharge amount, but your cable fella has not, then too you do not get the connection. They do not even extend the number of days, and charges are per day which is not told to you and if you do not use it for a day, you lose that day’s net connection charges.
