High Service charges only in 2020

I have been renting a property in kempton park since 2017. I would be billed services once a year. Since September this year 2020. It was first +R1500. I thought it's that once off charge but I remembered that I was charged in Jan. When checking the statement it was for June and August. Again after paying that on the 3rd, Came a charge 8 October Services +R1300, 1 November another one R+1200. Asked if this was correct and only dismissed with that's for water and other services. I asked why was this not billed monthly and why was I not made aware that there are billings that are delayed so that I can cater for them. If I were not to pay these they would cut off the electricity forgetting that I did not plan for these amounts. These are difficult times and as human beings we budget. Horrible service. I would not recommend them or buy any property with Jawitz Kempton Park. I sent them statements as proof of what am talking about. I have decided to move out.
