NSW Falsified Vehicle Log Book

[duckpond]

Hi, I recently bought a second hand vehicle from a NSW dealer and am pretty certain that the log books have been falsified. There is no such place as the mechanic on the stamp, no one on the other end of the phone knew anything about the so called business and on Google maps there is no such business. There is no phone number on Google for the business and no business by that name is currently registered in NSW.
Can anyone help please. Is this against the law to falsify car service records?

How old are the dates? It's very possible that the business no longer exists but did at the time(s) claimed.
