AI Summary
Based on 2 community reports
Calls to this Freephone UK number are reportedly used for impersonation of Nationwide Building Society. Community reports claim automated messages asking for card and account details after a text claimed a suspicious transaction had been blocked. In one report, the message stated it was from Nationwide Building Society. Both submissions have no upvotes, so confidence is limited, but the very high spam score (85/100) and the scam pattern are red flags. The tactic is a fake security check designed to harvest sensitive information. If you receive such a call, hang up and do not share card or account details. Verify with Nationwide using official channels.
