Caller: GetUp

Legitimate call...it was GetUp and left a clear message identifying themselves, why they were calling me and asked me to hold and someone would speak to me. All above board

I called back the number (02) 9052 8721 but the phone just kept ringing

Same as above.

Calls at least 3 times a day, no one ever leaves a message.

Brief call, I answered before it rang out, no message.

21:05 hrs South Australian time. Friday 15th Nov '19 . Called my mobile. I don't have contacts in NSW. Call was picked up and just silence, no background noise, Closed call.

Called, left no message, less than 30 sec'. Related numbers (02) 9052 8718 & (02) 9052 8719. Thanks for your posts.
