Caller: Scammer in London!!!!

No idea how they even got my number... lots of reviews about this number on SIA website stating it's financial fraud, that they want £500,000, they're customer service and first need to verify me with date of birth and bank account details. Also many people have said the caller is very aggressive and abusive. Somehow they got past my 'unknown caller blocker' software on mobile which is scary!!!

Rang twice so far this evening. When I answered there was no reply and they hung after a few seconds.

Caller: Scammer. They new my name!!!!!!

A British number. I listened without speaking first. I don't know what they are but how do they know my name???? Now I just hang up. I think it's some kind of fraud/scam.

Caller: Scam Call

Tried to call several times. My security installed on my mobile unmasked the number as originating in London, and a possible scam call. No message left. After looking on here, now blocked.
