Vodafone India — not providing exact information

Address:

New Delhi, Delhi, 110027

On[protected], I did recharge of Rs. 147 for the Data pack through the main balance from MyVodafone App. It was clearly written that I will be provided with 1 GB data but only 500 MB data is provided. I called the Complaint Helpline but they did avert me with the excuse that you get 500 MB only if you recharge with your main balance. But nothing of this was written on the app. So Kindly provide me with a solution or I will port my network.
