I called back number (03) 9832 0096 spoke to a guy who said company name is lynx connect.

Got called 6:17am Friday 18 March 2016, which is against the law for commercial phoning. Used "Reverse Genie" App and got map ref in Sydney but on opening map got position in sea near Nigeria, so likely a scam. These criminals obviously either don't know I am in WA or don't understand Australian time zones so a scam
