Discovery miles / pre paid electricity

Please note that it is impossible to buy pre paid electricity from Mossel Bay municipality with Discovery miles. I have an email from Discovery Bank were I was advised that they have a problem and cannot resolved it and that I should contact their service provider direct. I have contact the Service provider and they now have confirm that they can also not assist. With no options left I contact Mossel Bay Municipality and they advice that I use another company to facilitate the transaction were I have to pay a service fee on top of the cost of the electricity. Again with proof of the conversation. Who can assist with a proposal what I should do next ???? Please note that I am also unsuccessful to purchase the electricity with an Discovery EFT transaction or Credit card using the internet.
