First super scam

I got a suspicious message from this number... Please do not respond to it

I got

Question from my local GP clinic regarding vaccinations.

I got "Hi Gillian ,Pls confirm your app at 5:30PM, on Tue 27 Jun@ Ayurve MYER LVL 1 Reply YES to confirm NO to cancel 24hrs Canc fee apply (02) 8297 4844"

Grammar and wording seem funny, seems to be a scam to see if the recipient responds.
