Overcharged an estate regardless of meter readings

For months now I’ve been overcharged by Eskom even though I’ve sent them countless readings. I have also requested to change to rather to prepaid as to avoid being ****med by Eskom with the charges which it’s been months without any response from them. Every month before even receiving the statement of account my electricity is switched of just so they can charge extra fee to switch it back on. This is ridiculous to treat paying customers and *********. Spoke to different agents who could not help and all they could say it takes months for the change to prepaid yet when they want to switch off my electricity they do not even think twice.
