Had a message from this number that said "On 9 July 2018 we'll be moving to a new directshares trading platform" it say to not reply but click on a link. I did not click

The message read to confirm appointment with Dr Gau, I think the following day and just to respond yes or no. I don't know who Dr Gau or the medical centre is. The assumption is that they have the wrong number.

This is a reminder of your appointment with The Salvation Army Employment Plus Baulkham Hills tomorrow X at X.

Had an unsolucited message from this number with my own mobile number as the subject and a medical provider as the contact.have had no dealings with this provider.

Got an unsolicited SMS from this number, "Please call DIKE on 1300 074 359" and they included a reference number. Naturally, I did not call "DIKE".
