How do I buy prepaid water with Absa?

Could you please elaborate on the process of purchasing prepaid water using Absa? I'm interested in understanding the steps involved, from initiating the transaction to successfully receiving the prepaid water. Could you guide me through the necessary steps, including any specific requirements or information I might need to provide? Additionally, are there any fees associated with this service, and if so, how are they calculated? I'm also curious about the availability of this service and whether it's accessible through Absa's online platform or if I need to visit a physical branch. Thank you for your assistance in clarifying this matter.
