Supposedly an Uber Eats delivery driver. The message from Uber Eats said that this was his number. He picked up the food, then cancelled the order. When we called we were told calls were not able to be received by this number.

Caller: Uber Eats Driver

Not sure why he called but I saw him on his phone as he was walking in the driveway. Call hung up when I opened the front door. Assume any Uber Eats driver will come up with this number to preserve their privacy when contacting a customer.

I called back number (02) 9157 9634 rang once then gets disconnected automatically.

The call went to voicemail and they left a long robotic message about pension payments for Centrelink (I am not on a pension and have nothing to do with centerlink ).

Got a call, when I picked up and said "hello" and I waited for a couple of seconds without saying anything further... The call simply disconnected.
Looks like one of those scammers.

I called back number (02) 9157 9634 rang 3 times then goes to busy tone.
