I have purchased AirtelCallHome for $10. After lot of effort, I have registered myself. After that I got a confirmation of Registration.Since then I am trying to call my India Phone number. It is NOT at all working. I tried to call their Customer Service Center (1-877-247-5150 ). I couldn't talk to them. It is a total waste of money. It is NOT working. I want my refund now. Consumers beware. Don't buy this product. It is a total waste of money. Airtel has started this business without proper infrastructure. Their website is pathetic. I am trying for the last one hour to update my Phone number. Every time it is giving error.
