Reliance Web World — Deceptive deals for different customers

Hi,
Let me just describe the scenario first which has made me to write this.
This is the first time that I faced a setback which involves Reliance.
I had an urgent situation(Purpose: Interview) where I needed to open an account asap in reliance web world.
I needed it for one time only(max: 2hrs).I was told by the executive that I need to open a Rs 350 account(Internet hours equivalent to Rs 500).
There is no less priced package. But I knew there were other packages like 20, 50, 100, 150. I asked for the lowest amount package.
But taking advantage of my urgency, she made me to have the maximum available amount package.
Now, it been 2 months and they are telling that to recharge again with another 350 otherwise my Rs 385 balance will be lost.
If I recharge now, the balance would be Rs 885.Why should I recharge again?
When I wanted to inquire this with the manager. He was so rude and impolite that I felt humiliated.
I have made up my mind not to go to Reliance again. This was really embarrassing.
Please help.
