AI Summary
Based on 1 community report
This London number, carried by Core Telecom, is associated with a fake insurance scam. The caller claimed the recipient's Thames Water insurance policy was expiring, despite them never having such a policy. This is a classic scam tactic—creating false urgency around a non-existent product to trick you into providing personal or payment details.
With only one report so far and no community votes to establish confidence levels, treat this with caution. Thames Water is a legitimate water company, but they don't sell insurance policies through unsolicited calls. If you receive a call like this, hang up immediately. Never provide personal information or payment details. Check any legitimate bills directly by contacting Thames Water using their official number from their website.
