This is almost certainly a scam, so do nothing except keep an eye on your credit card statement in case your card has been compromised.
If you want to set your mind at ease, ask the “travel agent” for the last name used in the ticket and your PNR aka trip locator: this is the 6-letter identifier attached to every flight booking ever. Then call the airline or go to their website and check if you can find it: if you can’t, there is no ticket.
If you do find a booking, let the airline, your credit card company and the police know ASAP: the scammer will get more than they bargained for if they check in!
You should stay cool and double-check your credit card/bank statements in the next few days. If nothing shows up there, then you should be fine.
Every proper travel agency will not allow you to book a ticket online before they have your payment information. So they should not need to call you.
As your bank said, don’t ever give your account information to someone you do not know and who called you.
No one booked anything. You got a scam call, hope you didn’t give them your credit card information. I have no idea how bank statements or PIN code got into this mess.
