Turning off electricity *******ly terrible customer service dont rent from central developments!!!!

Cutting off power *******ly. I am living with my 65 year old father who has Parkinson's disease. We moved into Manor house in midrand almost a year ago, we paid a double deposit to the value of R30 000 and moved in. If you are slightly late with your rent they attach your rent amount that is owning on to your utilities account (electricity) so you sit in the dark with no power, can't wash clothes, cant cook food or do anything. We have paid R12000 of the R14000 rent and they say they are not interested and in order to have power again we must pay our rent. This is totally ******* but they dont care and tell you that you must run your finances better.
