Bad customer service ( ********)

I called the call center today and the agent was so rude to me instead of helping me with my query, she hung up on me!!! I honestly don’t understand the new billing system it’s just there to reap us off, I stay alone and I hardly cook nor use the water. I topped up with R600 and already I’m on a negative balance this does not make sense cause I’m staying alone and before R500 would last me the entire month.

I need this review to be checked because This is a reap off, there no way I would be charged R500 for water and sanitation
