PREPAID Purchase just missing.

I have paid R 1000 for prepaid electricity and never received a SMS confirming payment and a number to punch into my Meter. Although the transaction has gone through my bank it has not been paid to the municipality of Cape Town and therefore I have not received the electricity I have paid for. So trying to get onto the PREPAID 24 website to find someone to contact and they have a chat line which does not work. So it appears I have just lost R 1000. So back to the Filling Station I go to buy my electricity. I do not know how these companies get away with this. First transaction went through without a problem, second one on the same beneficiary has gone missing. How thats possible, have no idea.
