Spice Jet Airlines — Change in gate number also no information on screen about flight details

Address:

Mumbai Suburban, Maharashtra, 400054

I was suppose to travel from mumbai to belgaum by flight num#SG2647
by gate num 16
i was there before 1:45 boarding time was 14:20 but there was nothing displayed on the screen of gate 16 also there was no one standing at 16gate counter

(already checked on cctv camera as requested to airport police station)
proof:- can be checked in the cctv camera room of airport

these ppl say they shouted for belgaum but i didnt hear
as i was there in the 1st row but still dont knw how come i didnt hear may be i am deaf but i was not blind there was nothing displayed on screen at gate 16 nor anybody was stable at that 16 gate counter and they say they did boarding from counter15(gate 15) as mentioned before can check the cctv footage.
(why no display nor any message, nor anybody standing with the flight num written on the sheet of paper)
as there was one jabalpur flight delayed which was suppose to go b4 belgam n one man told us spice jet is always late... i am sorry i assumed the flight was late but for enquiry there was nobody standing on counter 16
