Caller: Scam - ?Spoofed phone number - allegedly Visa Mastercard

Caller with accent from call centre stated he was calling from Visa/Mastercard. Asked if they were speaking to <my name>. Indicated he had seen unauthorised overseas transactions. Stated there were transactions with Netflix and Amazon. Did I authorise them. I said 'No', waiting for the hook. Did I do transactions with these companies? Yes, Maybe. Then the caller hung up. Not sure if they got the information they wanted. I was waiting for them to ask for other details. Maybe the got the info they wanted?
