Unknown number silent when you callback.
Always block your caller id when calling a number like this. Today I had a fake Australia Post text and a fake ATO txt.

Another spam with saying calling from Simons

Multiple calls never leaves a mgs

Called several times for several days. On call-back "This number is not connected " message. I have blocked it

Wont stop calling 14+ calls

Called four times today. Left no message.
Returned the call and it’s silent.

Another caller who won’t leave a message
