Just got this email from UNISA, poor students have got little enough money as it is!
Dear Unisa Student

Unisa is aware of e-mails being sent to students that offer assistance with the registration process for a fee and upon e-mail receipt of their banking details. These offers are neither generated nor distributed by the University. Unisa will never request your banking details from you via e-mail. We hereby warn you against participation in this obvious scam.
