Got a message from this number regarding my CSC (ComSuperCorp) account. Complete scam.

clinpath account over due. i dont have a clinpath account

It’s a pool number from the company Whispir who is a messaging service provider. Lots of major clients which is why it could be from anyone.

Caller: Various legitimate companies (test messages)

Received legitimate text messages via this number; same number appears to be used by various companies for their messaging service

Do not know this mob

Caller: Automated SMS on behalf of different Jobactive providers

This appears to be a messaging service used by various companies and organisations including RACQ/RACV, Red Cross, Salvation Army, MAX Employment.
All messages received by me from this number so far have been in relation to appointments with Jobactive providers and useless (but legitimate) job ads said providers subscribed me to.

Do not automatically assume it is a scam. It is possible for scammers to make use of a service like this but there is a decent chance it is a legit message. It is certainly a little frustrating that spam and scams can come from the same number that legitimate companies use - as it can be unwise to outright block the number. But there are ways to protect yourself regardless.

If it doesn't give you any links to follow or numbers to call, it is unlikely to be a scam. Scammers want to trick you into giving them information. If they don't give you a way to contact them, they're not able to scam you.
If it does, and it's a company you recognise, use google to find their official website and contact details yourself and use them to contact the company and verify the SMS.

Jobactive providers will sign you up for job ads that may be sent via this service. That's why they have your details even if you've never heard of them.

Caller: Scammer

Why don't these scammers find something better to do than rip off honest, hard-working people. I hope they rot in hell!

Your purchase from Bunnings is on board for delivery with ANC. Job 75610300698333

I received a text from Melbourne Pathology about an outstanding account. When I contacted them they confirmed it was a legitimate message (sent to the wrong number).
I have previously received a blood donation reminder from this number.
It seems to be used by a messaging service.

I have received two texts from this number. Both legitimate. One a car park booking, one a car service booking from completely separate companies in different areas. Must be a reminder/appt confirmation service for companies who subscribe to the service.

RACV asking me to reconfirm address details
