You Broadband India — Poor network

This service provider network is so poor day by day
No proper support from staff,
Using their network, my brother was attending a job interview and the network was poor and suddenly stopped working,
He couldn't complete the interview amd he was given a second chance, now to our surprise he recieved mail stating he didn't select,
Believing the network and he started his interview and You Broadband screwed his job
Plan speed is 75 mbps and average bspeed i am getting is 4-5 mbps
