Sad Telephone communication with Aircel. Review on Aircel Mobile Operator

I have taken my Aircel connection two years ago. In that time the connection was good.The Mobile Operators were also good.But the connection of Aircel is getting worse day by day.I liked Aircel connection because it was cheaper than the other connections.But now these days I am having pretty much connection problem with Aircel. The network communication is very harassing.

Whenever I try to connect a call it crashes several times.Even during calls the connection crashes for several times.Network services are also very sad.Too much call delay.I also have some balance deduction problem.The Aircel operators never alert me about any types of service before activating it in my phone.When ever I recharge my account balance, they deduct the balance without informing me.So I am very much pissed off with the connection.If this continues then I have to leave the Aircel connection.
