Airtel — non activation of sim card till 48 h

We have purchased new sim on 29thsep oder no:[protected], was assured to get activated within four hrs. However, it is not yet activated (2nd oct, 8 am). We had spoken to customer service executives many times. After that we spoke to mr. Prasad [protected], but no use. Your customer service people appear to be dummies with no intention of solving problems but speak politely to fool customers. I regret to say that, your customer care is inefficient and disgusting.
