Oddly enough, the pattern here points to a classic silent‑call or automated drop‑off rather than a live scammer. Callers either hang up instantly or leave a brief recorded goodbye, which is a hallmark of robocall verification loops used by telemarketers to test active numbers. If you receive such calls, let them go to voicemail and avoid returning the call—dial‑backs often confirm your number as valid and invite more spam. Consider blocking the number through your carrier or a third‑party app, and report it to your national consumer protection agency. Regularly updating your call‑filter settings can also reduce future interruptions.
After receiving multiple hang-up calls, I called the number back and was told it was the Inland Revenue Department, which I do not believe.
During a call at my workplace, the caller seemed to be from a call centre but hung up when asked to confirm their number, indicating potential scam activity.
I recived two calls from this number today, the second time I waited and after 10 sec a robot voice said goodbye
Got a silent dial, no reason to answer.
