Scam/Fraud
01 Nov 2025
It appeared on my recents call list on my mobile phone, even though, I have not made any telephone calls from my mobile phone in more than 3 days, this is spurious & impossible as my phone blocks all unknown numbers, at my personal settings, if the number is not in my saved contacts, then its auto blocked, as I would not have asked them to call me & I certainly would not have rung them at all!! So BEWARE!!
