Airtel — poor internet service in my locality

Address:

HATHAURA, Siwan, Bihar, 841237

So many times we complain to the customer care and also requesting for airtel network booster but no one took any action upon it. I am having exams and my most of the work is done online and for that, i need a proper internet connection. The worst network ever.
I am very disappointed with airtel network.
I hope this will get fixed soon
Thank you
