Airtel — extremely poor network quality

Address:

Karimganj, Assam, 788710

Hello.
I wish i could scream and yell to you through email.
You guys keep sending us messages to buy airtel 4g hotspot at rs.999. That is okay.
But i wish you could put that much effort in making the network good and smooth. I have been using airtel 4g plan of rs.448 i. E. 1.4gb/day but good for nothing. I think you guys know well what 4g speed is like.
I have complained you guys about the network several times and you just keep on telling that it would be fine soon but when its gonna happen??
Tell me one last time.
Will you make the quality of the network good or should i port my sim??
I hope you answer quick.
Thank you
