Beware of Prepaid24 and the likes

I intended to purchase R100 electricity via Prepaid24 using my banking app . I accidentally entered R1000 and made the payment to Prepaid24. Immediately I realised my mistake and contacted Prepaid24 via online chat to explain my mistake and request my money be refunded. I was told that I needed to contact my municipality. I contacted the company that manages the prepaid meter and they were willing to assist with the refund to determine if I had used the electricity token or not but the municipality refuses to refund my money stating that they have a no refunds policy. The guess the consumer protection act means nothing to them. I can only imagine if a lower income household made this mistake or the mistake was greater than R1000, one thing I know is that your children will not eat for that month and neither the municipality nor Prepaid24 would be the least bit concerned. I'm never purchasing electricity online again and would rather purchases using cash at Pick n Pay or the local filling station. Don't say I did not warn you.
