Conned by Airtel-Lost the number as well as the money

Location/place: BANGALORE

Name of company/service: AIRTEL

I purchased an airtel prepaid number on 15-04-2012 in Bangalore.
When I went on roaming on 19-05-2012,they barred my incoming & outing calls plus outgoing messages without any prior information.
Then on my return & my complaint,they re-activated my services on 11-06-2012.
On 15-06-2012,at 2:00 AM,I was on a call,which was suddenly cut off & my number was deactivated from that moment with a pre-recorded voice saying “Number doesn’t exist”.
I went to an airtel office where the executive told me that my number is recycled and I cant get the number back plus the existing balance.
What a fraud!!
Cannot trust AIRTEL anymore.
