Midvaal Local Municipality billing incorectly

a 1 star rating should not even apply here. I had a high water usages due to spiteful people renting a flat on my property. I gave these people notice and they moved out leaving me with a water account of over R25000. In November 2019 I made arrangements with Midvaal to Pay the arrears over a certain time period My water was disconnected in December 2019. In January 2020 I disconnected from Midvaal water supply and have been using borehole water ever since. Yet every know and the I get notices warning that my water will be disconnected and two weeks later I get a notice that my water has been disconnected. Next month I get another warning if I don't pay they are gonna disconnect, and two weeks later another one saying I have been disconnected. I don't really understand what is being disconnected but they say the have disconnected the water. I have logged a complaint with the complaints department and asked that their records be updated and all the notice issue fees be taken off my account. Nothing has been done, a person can not speak to any one as every tells me I have to speak to the next person. I get no replies to the emails I send. I am wheelchair bound and I receive a disability pension only. I make payment on the account every month yet the amount does not go down due to notice fees being issued. notices I shouldn't even get.
