Aircel — Excessive bill charged

Address:

600081

My self Imran .R, I have been using many years and few year back I started to use postpaid connections with the number [protected].
Everything seems to be going smooth and occasionally they charge more amount with the name of VAS consumptions charges even though we have not use it.
But last two month the charging amount seems to be so high than my plan or usual payment of 400.
The month of June they have billed with the amount of 608 rupees and when I ask for the clarification there is no proper response for the customer care agents.
And few of them are little harsh when handling, and few of them are not to ready to listen properly, and when I ask to transfer the call to the next level they keep me hold for more than 30 minutes to make me to drop the call.
This sort of behavior's are not acceptable from the customer care peoples, since it is there jobs to serve for us and to provide a good service when we pay for it.
And many knowledge less peoples also exist, and one of them without informing properly or giving wrong information he has changes my base plan and from that incident only all these problem started to begin.
And whenever I make a call I had to explain every time to whoever pick the call in whether 121 or 198, but finally with out giving proper solution they end up the call with Software problem unable to look or we cannot help you in this situation.
I am not sure where is the problem whether it is with the Aircel or third part call center's.
If Aircel want me to continue the service had to resolve this issues or else I am ready to change the network.
Note: I have 2 postpaid and 6 prepaid connections in aircel. Everything will be disconnected.
