Today got a call from a hidden caller id and he asked me if I have called his number. I have not called anyone and he wanted to confirm my number which he repeated. I didn't entertain as I wasn't comfortable. But he kept calling. Finally, I told him I haven't called anyone and not to call me again. But he was very clear with my number. He said, he got two missed calls from my number in the last 5 minutes. I thought I might have accidentally pressed but there are not outgoing calls from my number at all.
If this is a scam call, do I need to inform someone ? or if there is an identity theft here? Or is there a possibility that some issue with the mobile network?
