@Optimus_Prime bro, you aren't even getting full promised speed in the day time. Railwire Broadband usually provides full promised speed as I have seen speedtest results by various users.
On a good setup by LCO,
Download speed should be 48-50 Mbps
Upload speed should be beyond your promised speeds i.e. 55-60 Mbps
And as
@Rushil bro said, only LCO can change this situation. CC won't do much help or even understand it. Unless your LCO is helpful, there is no other way to get these things fixed.
