They keep ringing & don't leave a message

Caller: Scammer

Recorded msg saying I had purchased a gift card and my account would be debited unless I cancelled the order for the card. Obviously I did not order a card. Scam.

Missed call, called back Said they were from eBay and someone had used my phone number to set up an account... told them to take it to fraud department I haven’t used my eBay in months, she had nothing to say in response so hung up

scam call. I rang back and they said I had received a gift card
