Airtel — unrecognised transaction successful for prepaid mobile [protected]

Address:

743435

I tried to recharge a prepaid mobile [protected] on today afternoon and the transaction also successful but on this above mobile i got a sms from erchrge that "bill payment of rs.149 successful with receipt no." (Screenshot attached). No recharge done. I want to know that what is the bill payment of any prepaid number? Which receipt number is this? What type of transaction is this?
Next i retried for recharge again and recharge successfully but money deducted twice.
