Query about a deposit transaction to account

I was checking my account statement and there is a deposit of 1000 INR which I dont remember doing.

The transaction description is RPOS-(my debit card no)-(transaction id(I am guessing))-04-03

Any idea where this transaction might be from?

PS: If the last detail is date I only did one 1000 rupee transaction on paypal on that day which was successful
