I have got my sim changed (bcs of regular network loss )from your service point at iris tower shona road, gurugram on 27/11 afternoon but till time it has not activated & your customer care rep is saying that it will take another 24 hrs. what is this ? this is highly irresponsible of airtel. as soon as my sms get activated i will port my number.
