AI Summary
Based on 1 community report
This London number appears to be impersonating O2 with calls claiming to offer discounts for network issues. The caller was based in what sounded like an offshore call centre, which is a common scam tactic used to avoid detection. The offer of a "substantial discount" without you having reported any problems is suspicious—legitimate network providers don't typically cold call with unsolicited offers like this. You did the right thing by hanging up. If you have genuine issues with O2, contact them directly using the number on your bill or their official website rather than responding to unexpected calls.
