Airtel — Want to cancel my sim order due to the lack of information provided by Airtel.

I ordered a prepaid sim card. After I ordered it, they notified that I will have to pay extra Rs. 100 just for the deliver charges. This made me frustrated, things like this should be mentioned early on. I would gladly go the Airtel Centre instead for a Sim. I'm a former Airtel user who wants to continue and this go this way.

I hope this gets dealed soon and my order is cancelled.
