Internet scam is everywhere and in every country, so shutting this business down won't do them any harm. Simply, they will start over. The problem is in the South African government, most of the online scams originate from corrupt or undeveloped governments (China,Nigeria,etc). The government needs to take actions against these people,otherwise they will continue until they fill their pockets. However, you can hack the company's email, the one you posted and from there you can deal a massive damage to their operations.
