Airtel — worst network and internet issue

Website:

Airtel

Worst networking. I'm unable to call due to worst network and sudden call cuts. Very very importantly worst internet access of 4g. I don't know is it really 4g network they are providing or 2g network. Even 2g also work fast compare to this 4g airtel network. Really the worst network i'm seen and i really like to tell the people don't use this worst network. Is it really 4g network!!! The worst network i'm experiencing. I[censored] don't reslove this problem, i will make it viral news in social network and promote people to switch to other best networks available.
