When you sign up and add your debit/credit card or when you add a new debit/credit card, a temporary hold is placed on your credit or debit card for a specific amount (usually R1), used to ensure your card is valid before you are able to make use of the service.
This is not a debit, and we will not convert this temporary hold into a charge, instead it should be voided by your bank within 10 working days. However, we unfortunately do not have control over the different issuing banks and their timeframes.
