Airtel — network issues in calls and internet

Address:

South Delhi, New Delhi, Delhi, 110044

I have been using Airtel Prepaid connection from last 3-4 years now.

i live in pul prahlad pur area near badarpur.

i have ported my sim from Reliance to Airtel thinking that its is a good service provide in networks while there plans were also higher than others.

now i have also changed my smart phone if it has any problem but actual problem is in Network .

Even calls drop almost 80% times even when i am using 2G network .

I am even mentioning about internet which is gone worse than that .

Call drops when my phone showing all the network sticks.

All these problem occured from last 6 - 8 months. there customer support says that network coverage is strong in your location then why call drops .
call were even droping while i was taking to there customer support.

they are not even looking to resolve this, And this is not only my problem every friend, family and people in are have same problem

I am moving from Airtel to any other network.
