receiving emails advising of security codes after accessing various online accounts

sending security codes we haven't asked for.

Scam ... 2 security codes not requested. Suspect someone trying to purchase on my card details. Bank notified.

Same....SCAM a security code I did not request.

Keep on getting msgs - not phone calls - saying Payment Receipt Number ..... Registration Term: Annual Amount Paid: (almost $300). Have checked my credit card - nothing withdrawn.
I would say SPAM

Caller: Service NSW

Was an SMS from Service NSW to reset my password. Legitimate as I was talking to them to reactivate my account after I was unable to use QR codes while shopping today.
All good.

Security code to verify mobile no for Service NSW account (dont have one!)

From 0480 013 624
Your Security Code is ###### (where ###### = six numbers between 0 and 9)
It started exactly 8:00 PM AEST. It stopped exactly 9:00 PM AEST.
There were 11 messages in total. I've subsequently placed 'Block Caller'.
I used a different phone to call the number whilst it was spamming me. I got a 'female' sounding robotic voice advising:
Thanks for the call. Configure your numbers' voice URL to change this message. Let us know if we can help you in any way during your development.

I received a message from this number saying "Your Security Code is 989336" and I didn't ask for any code!

Used for new password from rms
