Nextra Teleservices — To set up new connection

Sir, i got a new connection before 2 days.
But your engineers not setup wifi and they also taken payment and share verification screen shot, now balram is saying that i don’t give connection in your area.
They should deny me for new connection if you don’t give connection in my area.

Please tell me what is it?
Please confirm can they get connection in my area or not?

If not please refund my payment, after that i’ll get other fiber connection.

Please resolve my problem in half hour.
