Airtel — worse support worse network worse resolution and above all don't keep the privacy

Address:

Kolkata, West Bengal

I have been facing issues on getting my personal details available to people which included my call details as well as my location irrespective of repetitive complains no action taken when i wanted to disconnect the line they called me multiple times and asked me to stay. They share all information to anyone and everyone no privacy is maintained and when reported they don't take it seriously.
Now on data having a 4g connectivity on data card hardly i get 4g speed everytime when i complain they send a person they checks and say there is an issue and it will get resolved, today since morning instead of having 15g of data left the connection is very low. After calling up the call centre they started saying they are unable to check then check if sim is inserted all sorts of timepass question when i was bit harsh they said they will give a call back. Worse organization not sure how they are promoting fastest network they should say worse network and worse customer satisfaction
