Block unsolicited numbers immediately to curb persistent harassment. Repeated hang-ups signal potential scam attempts or automated dialing systems testing active lines—don't engage. Enable call screening on your phone or app to filter unknowns; report to authorities like the FCC if it escalates. Verify any callback issues aren't from your carrier; use tools like reverse lookup sites cautiously, as they might not always pinpoint sources. Prioritize privacy by limiting shared contact info online, reducing such intrusions overall.
Our Head Office received repeated calls from this number; each time the caller hung up, and the line shows as "number not recognised" when we try to return the call.
