Error in Municipal Bill Payment

the cashier made an error with m rates payment and paid it into an Eskom account. this is no error of mine. She punched in the info manually. Now the transfer will take 6 months. This is unheard of in this day and age. The municipality does not want to understand and this places me in a disposition. Management said they will call me on Friday, 2nd of June, 2021, still no call.
