Nextra Teleservices — internet not working from last 3 days

Gurgaon, Haryana, 122001

My complaint no are [protected] and [protected]. Still not resolved. I complained on 26th august and 50 times i have called customer care and every time they responded your problem will be sorted in 6 hours and again and again every time they tell that technician is assigned but technician never visited.
Worst is they send you message that ticket is resolved however it was never resolved.
They said we have highlighted and escalated your case but they never have any update about the complaint, i m doubtful that they have any technician i their team. It's a junk wifi which never works. I am tired complaining but i don't honk they will be capable of solving this.
