Airtel Prepaid — My connection

My phone number is[protected]. I have been using this for the past few years. I had taken a life long connection and i have ensured that there is enough credit balance through out. However, Now after some time when i switched on the mobile, it shows sim registration failure. Please ensure that it is sorted out within 8 hours. I am boarding the flight in another one hour. I need the connection to be restored before i land there to avoid me going to the court against airtel. I am on holidays and i confirm that i have the time and patience to go to the court against you if it is not corrected by the time i land there.

Thanks,
Sasrik Sivaram Vallath
