[Resolved]  Idea Cellular — mobile balance is charged on calling a toll free number

Hi,
After calling a toll free number[protected], from my idea cellular mobile ([protected]), the account balance is deducted totally and the call got disconnected. Upon inquiring with the idea customer care executive, the first person (Koteswararao) who received my call, couldn't answer why the balance got deducted and responded like he'll transfer the call to his higher executive. And after the call got transferred to his senior (Sheikh akbar), he responded very vaguely and suggested me not to make any calls to the toll free number.

Here, i just wanna know why the network providers are looting people by providing less information??
