Bill Miller, it is possible they did have a missed call from you as scammers do something called ‘spoofing’. This is where a scammer will call someone and the number that shows on the phone is a random number they have chosen to use instead of it showing the scammers real number. It is possible that the person received a missed scam call that showed your number as the scammers were using your number as a spoofed number. Please google phone number spoofing to find out more information.

They called from this number saying , missed call but no record of a missed call from that number.
