Running out of electricity with no payment option

I app**** for a new electricity account in Dec when I was moving. First time I wasn't given the right information, had to go back twice to get it sorted, was given different info every time. I also app**** for prepaid, they didn't pitch when they said they would. When I phoned them, they just made a new appointment, with no excuse no explanation, no sorry for the inconvenience. They eventually came to put in the prepaid meter, and no instructions given. The tech guy just shoved a piece of paper in my hand and left, I have no idea how it works. I've been trying to buy electricity at Spar and PnP, they keep saying the account doesn't exist. I tried logging into the website, the password they gave me isn't working, I first had to reset it. I tried buying electricity via sms, no response received. When you phone them, they don't answer. I am quite fed-up, and I'll be without electricity soon with no means to do anything about it!!!!!
