Average mobile operator. Review on Aircel Mobile Operator

I am using Aircel connection from last 5 years. Aircel gives always better offers but their service is not good at all. When data balance is low they don't even give message or notification, for this when data is over cant know and all main talktime balance goes away. I suffered this many times. Value added services are too much irritating. Everytime I asked for stop VAS and after some days it activates again. Network and call quality is good in my location but sometimes network bars are disappeared suddenly and I have to search network again or switch off and on the device. Customer service is not up to the mark. Holds for long time during communicate with customer service executive. Charges are reasonable but their extra balance deduction is pathetic. They should fix it. Net connectivity is okay for recharge price and in terms of 3G data. Now I already linked aadhar number with aircel still every day I receive at least 10 messages for aadhar link. Dont know why.
