[CAN] China Eastern airline called saying I cancelled flights

I got a call from china eastern airline which I’ve long time before booked tickets from before, saying I booked multiple tickets and cancelled such tickets 2 hour before flight.

I was on the call for 30 min entertaining the idea that this was a fraudulent activity done by someone else until I realized it may be a scam call. However the phone number matched up with the china eastern line.

They had my “nickname” and last name and stated that I must have booked it because it was booked with my information and ID. But it was booked in Shanghai which I haven’t been in 10 years. They were threatening blacklisting my name for travel.

Only reason I stayed on the call was because I did lose my passport for a day abroad in Japan but got it back the day after.

Eventually I had to leave for a meeting and said I’d call back. I then called back 30 min later and china eastern said they would never call me so it was a scam.

I didn’t give any of my information such as legal name, birthday or anything like that except confirming I didn’t make the ticket booking and that I live in Canada and was in Canada in April. Should I be worried about anything?

Thanks!
