Waste of time online prepaid services

<p>I have tried purchasing prepaid electricity twice now without receiving my voucher number. This is extremely frustrating considering that this service is supposed to save time when instead it wastes it. The last time I had to call to retrieve my voucher number. Today, I've called again to receive my voucher number. I waited for 20 mins to speak to consultant only to be told that I will be transferred to another department of which waiting times are unknown. I waited a further 30 mins to no avail. This is so unacceptable. I may as well have driven to a shop to buy electricity. It would have saved me both time and money considering how much I've spentried on the phone calls. Now, my money has already been taken and I sit without electricity at home. Standard Bank should not be offering a service which they cannot provide. Horribly disappointed. </p>
