SBI — Doubtful transaction

Address:

Mumbai City, Maharashtra

Dear Sir,

I booked my ticket on IRCTC using SBI net banking successfully, meanwhile I found one debit entry of Rs. 100.00 with narration "POS PRCH - POS[protected] Billdesk.com SBIPG". I don't remember any transaction I made using Billdesk except booking ticket on IRCTC.com

I like to know what for this amount has been debited and who is beneficiary of the amount and how beneficiary able to debit my account

Regards
