Spoofed numbers. There is a scam going round where the spoofing software replicates numbers near to the one they are calling. In the first case the software got it wrong and hit on yours.
I got one yesterday very near to my Vodafone numbers and a week ago my partner got one very near to her EE number.
At this stage nothing Virgin can do. However, the telecoms industry is working on a solution that should work across all mobile and landline networks
