My mobile number has been spoofed and the fake one has been ringing lots of randoms

[PurplePeach62]

Basically starting from around 9.30am today I've had 15 calls from landlines around the UK saying they've had a missed call from me. I haven't rung any of them and my supposed calls to them aren't showing on my call log.
I've contacted my phone provider who weren't particularly helpful saying they couldn't see any unusual activity on my account.
I googled it and it's a thing and called spoofing
Can anyone suggest anything I can do please?

It looks as if maybe you report it to Action Fraud. However, I would query whether your number really has been spoofed, or whether a fraudster is trying to make you think it has. It doesn't seem very likely that people are en masse seeing a missed call from your number and calling it to find out who you are - does anyone really do that? Did they sound plausible? I wonder if this is phase 1 of the fraudsters telling you you've been a victim of identity theft.

I'd be tempted to send all calls from unknown numbers to voicemail (and change your message to say your number has been spoofed, you haven't called them) or just block all calls from unknown numbers for a while and see what happens.

This happened to me last year. I even got a call from my own number to my number 😂 they use them once or twice so it should die down and not happen again!

Tribpot - great idea about blocking unknown numbers and the voicemail message.
They do sound very genuine even to the fact they have the regional accents matching the area they're calling from. In fact a couple tried to explain in detail who they were to help me remember phoning them
They all sounded in the older age bracket which explains why some have returned the calls I guess.
Anyway it's been quiet for the last hour so fingers crossed- until people return home from work and check their phones!
Thank you for your help

That's reassuring in a way, hopefully it will stop by itself - will update if I phone myself

This happened to me - my provider just said that there was nothing they could do - it would either stop in a couple of days, or the 'spoofers' would use it for longer and I could change my number. Luckily, it only lasted about 24 hours, but I had some quite irate people shouting at me for phoning them multiple times....

Oh dear! My worry is that I'll 'ring' people in the middle of the night and worry them - I've just listened to a voice message from a very elderly man wondering what I wanted.
Can't see what people gain from it!

The scammers need to rotate numbers frequently as they get reported as spam. So I guess this keeps them from being blocked by people with spam filters set up on their phone.

@PurplePeach62 There is a website called "Who called me?" and you can put in numbers that phone you and it will tell you if it is a scam - I entered my number in there and said that I was very sorry, my phone had been spoofed and please ignore calls from it, but there was nothing I could do and it wasn't 'me' phoning! Calls stopped very quickly afterwards, so I don't know whether that helped or not. It's really horrible - hope your number is moved on quickly.

Thank you all for your advice and comments- I'm pleased to say the calls stopped as suddenly as they started so hopefully it stays that way
