Someone called me from an unknown mobile number and I answered. They asked who they were speaking to. I said they should know as they called me. They said they were calling me as they had a missed call from me earlier. I said no I hadn't called them. I said let's put it down to a misunderstanding.
Then they texted me a screenshot of my call to them but I definitely didn't call as I didn't even have my phone with me at that time (it was in another room, charging) and my phone doesn't show a call to that number.
AIBU to think this a scam? If it is, is it the person calling me or is it possible someone else has called them using my number?
