send email with Thailand email address saying appointment made for 17th July 6:30 PM appointment at Nth Sydney for full body scan at cost of $1800 to cancel I need to call guessing scam email

Caller: Email only

I received strange email about unsolicited very expensive medical scan appointment for today. I checked and doctor exists and respected, but appointment was at the Mater not his listed surgery. Obviously a scam as it needed funds transfer! The above phone number was given which is why I checked in reverse australia site.
