Why are they so dishonest about their water tariffs?

I am paying R77.00 per kilo litre of water on citiq prepaid water meter. They say they set your tariff according to your municipal bill but this is untrue. I have spent hundreds of rand talking to multiple agents who all tell you something different. It's like they just tell you what you want to hear. One agent told me I was paying R27.00 per kilo litre. Not true. After a long conversation with a gentleman named Kamo which included a conference call with my landlord he assured me I had been on the highest rate and was now on the lowest. I bought water and discovered I was now on an even higher rate. My municipal bill is R700 pm. I have spent over R1500 on water tokens this month. I asked the last agent to escalate the problem because I can't deal with all the misinformation. No response as yet. Just spent 10 minutes waiting for someone to answer. No response. This company behaves like a government department. Avoid at all costs!!!!
