Got a text asking me to call back and confirm an appointment I have no idea about and to not reply to the text message.

Caller: My Doctor's appointment confirmation service

A legitimate SMS message asking me to reply 'Yes" to confirm my doctor's appointment next day. I get this the day before the booked appointment each time I make an appointment so they don't waste their time waiting for a patient who does not show up.

Purported to be Mr Pullen in East Melbourne. No specialty. Asking to confirm appointment.

Caller: Multiple companies

I have had legitimate SMS messages from several different companies on this number. It probably belongs to an SMS service like messagecloud.com.
But that doesn't mean it can't be spoofed, so if you get a message you weren't expecting, don't click on any links in it.

Called from a private number first. Then asked me if I knew a certain individual (which I did). They then asked me to contact the individual and ask them to call. The caller then text me from this phone number with a landline to call back on.

The text said (2/2) notice required. Didn’t reply.

Messaged me that I needed to update address via a link to receive parcel from fake company. DONT CLICK THE LINK! Obviously scammers

got a txt saying that they left the key under the doormat.
No idea who they are. blocked the number.

Text message saying I haven't completed my anti bullying and WFH induction for a new job that I'm supposedly starting next week. It requests me to message STOP to unsubscribe. Won't be replying.

Caller: No idea

Ms. Shamoli, go to an address in St. Kilda

Received a message stating that I would get a call about a medical assessment for a disability pension. Then it said "Please do not reply".
WTF ?????/

Came from Anytime Fitness. They keep calling despite me opting out with "STOP"
