[Resolved]  Aircel SIM Card — not stopping the connection and sending bill

Address:

Mumbai City, Maharashtra

not stoping the connection and sending bill
I have taken postpaid Sim card of Aircel in November 2009
service given to me was:
mobile no is [protected]
1)30 paise/min local call
2)75 paise/min std call
3)1500 sms free
with the monthly rental of rs 200+1000rs for starting connection with assurance that it will refund when i will close the connection
but when i receive my first bill my std charges was calculated as 1.50 rs/min while paying the bill i make complain about it. they said it will be cleared in next bill. but next time the problem was same so i again complain about it at that time they said "you didn't complained about it before we are taking your complain it will be sorted out soon '' i told them "first clear it then only i will pay the bill else close the connection"
problem was not clear till the month of jan and receive bill of amount near about 800 at that time i visited aircel store tell them to stop the connection but they are saying it cann't be stop before six month and you have to pay monthly charges till six month .and after that my out call service was stopped by them.
but in the month of march i receive bill amount of rs 2,130 which include previous month charges + 899rs for out going calls

in-short :
1)improper calculation of bill
2)not stopping the connection
3)sending bill per/month even-though it is not using by me
4)this month i receive bill of amount 2130rs which was not used which contain 899rs for out going calls{out going service was stopped by them in month of jan}
