Airtel — pathetic internet in the name of 4g

Address:	Pune, Maharashtra, 411027
Website:	www.airtel.com

I raised internet network issue request with airtel number 121 on 6 aug and they assigned me two service request 78424116 and 78424341. Its still in progress and no one has contacted me yet to resolve the issue. I called the helpline number again today and now they say we will look into this.
When they ask us for the bill payment we should not be late as then they will charge penalty. Then why not when we face issues like this such network operators should be charged for there lenient attitude
They make so called postpaid promise and they are yet to offer basic internet facility, i am paying for 4g and not even getting a 2g internet
