AI Summary
Based on 1 community report
This London number, carried by Colt Technology Services, has been reported for impersonating O2 and requesting bank details over the phone. The caller claimed to need payment for a PUK code (the code needed to unlock a SIM card). This is a classic scam tactic — O2 will never ask for full bank details or charge you for a PUK code over an unsolicited call.
With only one report and no upvotes yet, it's difficult to assess how widespread the issue is, but the description matches known fraud patterns. If you receive a call from this number claiming to be from O2, hang up immediately. Contact O2 directly using the number on your bill or their official website to verify any account issues. Never share banking details with unsolicited callers, regardless of who they claim to be.
