Caller: 'Mole Screen Australia' supposedly

Left message to return a call from Shayley
Called back as I had recently had a biopsy and assumed that they were related.
Was asked to select which State via a number and asked for the person. I was greeted first with what is the residential address for reference, which I sadly gave, then was asked if it was in relation to an appointment. My reply that I wasn't sure but I had been for a biopsy the day before to which they hung up instantly.
Tried to call back and received an engaged signal each time. Hopefully no damage done. Blocked
