Appalling service

On 28 February 2022 at 11:19 in the morning, I settled my account R1890. Today I bought R1000 pre-paid electricity. To my surprise out of R1000, I was only awarded electricity of R347.83 which is only 167kWh. When I called I was told my account is in arrears, yet I made the payment two days ago. I was told there is no one in the Creditor's department to help me. I was also told that I will have to buy more electricity since they will not even give me the outstanding amount. I then informed the lady that I will write to Hello Peter. I requested a ref no. ***. The city of Tshwane like many municipalities is a law unto itself and no one is standing up to them. The citizens of this country have to keep quiet while they are exploited. Where do I get another R1000 to buy electricity?
