INCOMPETENCE OF TSHWANE MUNICIPALITY ACCOUNTS DEPT

I am very much disgusted with Tshwane municipality billing department as many of us are paying our accounts on monthly basis while others aren't even honoring the bill but we get to be disrespected in this fashion...my account is paid upto date and i am literally unemployed but every month i know my dues and honor...this account is of my late mother and since i am left incharge to payin the rates and services i do that via EFT but is is never allocated on time and always when i buy electricity it will be reduced claiming my account not being paid whatsoever...right now i made my payment beginning of Jan for Dec but upto now it is not allocated so that they can add hidden charges which will not be reversed...can this looting be dealt with once and for all at this municipal office...every time i buy electricity units, they come reduced and having taken my money i use to buy units they say they paying portion from it; then they block my purchase of units i was supposed to get...i can't stand such incompetence every month from the accounts department...i want answers as this is very offensive to me...I WANT THIS MATTER RESOLVED A.S.A.P
