PRABOA is a Public Benefit Organisation and has to stick to SARS rules. Among these are NO REFUNDS. So we cannot reverse debits if you have already left!
Please let us know as well as Cortac. A simple email to firstname.lastname@example.org is all that is needed. Please send it in the first half of your last month. Then I will usually cancel you by return of email. If the cancellation comes after the debit order run has been loaded (often about 22 of each month) you cannot be refunded.
