I was sold 5mbps fibre optics line. They did install fibre optic cable till modem.
But speed was never more than 128 kbps. The ISPs own bandwidth is not more than 10 mb while they can sell you even 25 mb line. Beware of these cheats. Do not waste your money with this ISP.
Connection goes off every two days. No one will pick up customer care number if no connection. They will never send bill, you are expected to pay.
Even if the connection is not working for a month they will keep you billing.
