Airtel — deactivation internet booster

Sir,
I, vinay alaparthi, am holding a postpaid airtel number [protected] of mysore, karnataka. For the last two months i've been trying to get a booster pack of 1gb + 2gb deactivated from my plan but the airtel service people only assure me that it will be done in half hour without any credible action being done at their end. Every month i'm forced to pay rs 350/- extra on my plan because the airtel service people are not deactivating the 1gb + 2gb booster from my plan.
You are requested to immediately cancel the both the booster plans from my postpaid plan otherwise i'll be forced to change over to a different service provider and file a complaint against airtel.

Regards,
Vinay alaparthi
