Why does 0285285509 call and leave no voicemail?

Should I call back 02 8528 5509?
No. Do not call back 0285285509. Returning calls to numbers you don't recognise, especially those associated with silent calls, can confirm your number is active and may result in more contact. If the call is legitimate, the caller will leave a voicemail or follow up through proper channels.

Most modern phones have native call-blocking features. On iPhone, use the block option in recent calls. On Android, use the Phone app's settings to block contacts.
