Access and charges

I haven’t had access for 2 months and Derrick Baloyi who is supposed to assist me doesn’t answer his phone and doesn’t return any calls. The only day I got ahold of him he placed me on hold for long cause he was on another and dropped.He never tried calling and calling and sending him messages doesn’t work. I also have an issue whereby I was charged R70 on my electricity as “arrears” but I purchase my water, when I called I was referred to Pretty who said that she’ll investigate but has never got back to me and it has been a month. I have been very patient but it seems like the staff members don’t want to do anything about it
