Airtel prepaid money deducted but not recharged
I have recharged my airtel no[protected] for Rs 399 through sbi online banking.Money has been deducted but not recharged.I didnt get any message from airtel.Transaction reference no is UH38566121. My name is Deepa and account no is [protected].

Today someone from this number[protected]called and said calling from Airtel customer care, asked my debit card number for refunding the amount and I have given my card number.After that I feel suspicious...
