Airtel / 3G Wireless Internet — Wrong billing cycle affected my costing

Address:

Gautam Buddha Nagar, Uttar Pradesh

I have purchased 3G wireless internet standard plan of Rs 450 on 11 th August '12. As per the plan my billing should have been(Not explained) one month but billing was done on 24 th Aug'12 thus reducing the @G benefits to 1G and charging at exorbitant rate for the rest of the uses which under signed had used within 2 G plan. Instead of paying Rs 450 plus taxes , i had to pay Rs 1200/- thus loosing due to adroitness on part of airtel.
