Billed for service they didn't do

Received electricity bill for R1865.38, went to the municipality to inquire why my bill was so much. Spoke to a lady, she told me that my electricity bill for this month is R974.48 and the R890 is the disconnecting fee that took place on the ***. Told her my electricity has never been ,tried to explain it to her that I don't understand why I have to pay for something that didn't take place. She didn't help me at all. Went back today spoke to Daniel makhubela he told me they can't reverse the money since on their system it show that it was meant to be switched of. Told him I paid on the 14th day and he told me it can take up to 3 days to show on the system, I asked him how is that my problem since they never told us about that, he sent me to a lady. Spoke to her told her the same thing I told the others. She seem to understand so she sent me to Rider, he told me to go to the police station to get affidavit. Got the affidavit gave it to Rider, asked him to give me some kinds of proof to show that I gave them the papers to run investigation, Tumelo told me I have to take their word. And I have to pay since investigation will take 6 months. I need that money reversed
