MANAGEMENT PROBLEM

I live in Little Manhattan unit 90 In December I bought R200 electricity and grade control added another R200 without my consent. In January they deducted R200 from my account without notifying me. When I was loading my electricity account only then I notice that my account was on the negative balance so I had to sit in the dark with a sick child for a whole day. And this is not the first time this has happened and nobody explains why or how this happens and how they will avoided such things happening in the future. On the 26th of January early in the morning I added 300 in my account and now it is the 27th of January and my account is still not been loaded with that 300 Threads that I loaded yesterday. Every time you load your electricity account they ask you to send proof of payment I don't know why we need to send this because the reference number is on there but I did this anyway and my electricity bill is still not been updated. I have been trying to get hold of them since yesterday and they've been avoiding my calls and ignoring my WhatsApp messages. Somebody needs to be held accountable for all these mistakes that they have been doing. Running this company as if it's a ****a shop in the location someone needs to be held accountable for all these mistakes. If they can't do their jobs just move me to prepaid electricity.
