I deposited it at the decadent store, but they keep telling me to deposit it

(1)Account transfer to a decadent business
(2)I was told to deposit 501,000 won in the form of a deposit
(3)The name of the person who made the reservation was wrong, and you need to deposit 501,000 won to get a refund
(4)The price has been going up since then, and we’re asking for 300
(5)I don’t know because I’m a beginner, but the virtual account system of decadent businesses
(6)Is it going to work or is it a scam
