Idea Cellular — recharge cancellation

Address:

Chandigarh, Punjab, 160047

I recharged my idea sim with wrong plan today. I tried to contact idea service care and in return I got nothing. All I want right now is to downgrade my recharge plan of my choice so I can get my value for money. Either I want to get my money back into my account or I want my plan to be changed. I will be very much thankful.
