Ridiculous fees and bad service

I stay alone and I am going through almost R1000 electricity and water a month despite the fact that I am not even home very often. I don’t understand how this is even possible? A lot of people in the same building as me have the same problem. My girlfriend also stays here and her and her brother are spending nearly R2000 a month. It was understandable that we used more during lockdown because we were home most of the time but we have been experiencing this since the beginning of the year and actually haven’t even seen that much of an increase since lockdown. Various people have complained multiple times and nothing ever seems to be done about it. I believe there is something wrong with the meters in our building.
