prosperity group international

Has anyone had any dealings with a company based in queensland called properity group international. in particular has anyone taken them up on their offer of index trading, and have succeded making the money stated in their contract of a minimum $10,000 in six months.
An up front fee is payable of $5775 and the balance of another $5775 is payable once you have reach a profit of $10,000 in six months. this company offer 5 indicies for which you get sms alerts on to trade on a platform which is classed as betting which you do not have to pay any tax since it is a windfall just like you won some money from the TAB.
Their stretegy is to bet on a particular index to go up or down within an hour by 0.03 of 1% (0.0003%).
If it does you win about 98% of what you intially bet.
If you lose you must double up your bet until you win.
Working on a $100 dollar bet, your next bet is $200 then $400 then $800 then $1600 on your fifth bet to give you a profit of your original bet of $100 of which you get $98 profit.
In my eyes you would need to do 10 trades per week to acheive $980 per week and $25480 in six months of which you must pay back $5775 for this to be worthwhile doing.
They state on their website www.pgi.net.au that During the past 12 years of trade alerts, PGI has never had to double up more than five times consecutively, meaning that we have ALWAYS made a profit on every single trade.
They have nothing to do with your trading account and you can bet what you like.
Is there anyone out there who is a client of prosperity group international located at Office 1A, Level 1 and Offices 9A and 9C, Level 4, 128 Bundall Road, Bundall, Australia.
