before when these types of calls started from nigeria o2 someone started a thread about calls from nigeria , that 02 was looking at , i myself was charged for calling back the number, and because of the thread o2 was looking into fraud, by just replying to the thread o2 acted on it the calls stopped and i was reimbursed the money
i had blocked the number but they just use a different number so blocking isnt working
i started this thread to be helpful and that maybe it had started up again
There is no fraud hotline as these calls are nothing to do with fraud relating to O2. If they were, this would be the advice you would follow https://www.o2.co.uk/help/safety-and-security/phishing-and-smishing-advice
However we do have a community guide on spam calls and text Guide: A Guide to Deal with Spam/Scam Calls and Text
Though blocking does mean they will eventually give up. They are set up on an autodialler and pick random phone numbers. It's time consuming but you have to persevere with blocking.
