Scammer! These scammers tell you that you approved an ad for publishing and then charge you. Completely incorrect. They even send a reasonably impressive looking magazine with your ad. Only problem is that there are major errors which clearly indicate that the ad has never been provided to them nor proof read. In fact, they just pull the information off the net and other sources but end up with wrong logos and business details. Dead giveaway. Then they have someone call saying they are from Charles Sturt University to legitimise the publication. Almost clever if they were stupid! Here is a link to a similar scam by someone who was caught. Soon we will see this guys busted when ACCC investigate them. BE WARNED! 100% SCAM.
