UNEXPLAINABLE HIGH WATER BILLS AND IGNORANCE OF EMAIL AND CALLS

After complaining about my water bill, sending emails, and calling...Mbali Hlaula from Mafadi blatantly ignored my emails and only responded with the statement I was initially querying about, advising me that is it payable before the 1st of October. I called her using my cell phone, she never answered, I decided to use my work telephone and she answered told me there is an error and that she will check and call me back. She NEVER did. I called her again she is not answering my calls and is now ignoring the Landline number. I called their are offices and spoke to Tendani and they are giving me the run around with no answer. Why is Mafadi still allowed to operate when the overall customer satisfaction is 1 star??? Am I going to get answers ???
