Being charged over R2000.00 a month for electricity that has been cut 4 years ago already

Dealing with the City of Tshwane municipality is the worst and most frustrating thing ever. My account was overdue so they cut my electricity 4 years ago. I was told to pay an amount, which I did and paid more than required. (The money was loaned to me) when I contacted the municipality I was told it was too long after I'd paid and had to pay again. Well I couldn't loan any more money as I'm a pensioner and just don't have a regular salary. In the meantime I have been billed for almost 4 years now for electricity that I don't have. They have been estimating my readings for about 20 years. I've been to so many offices to try resolve this issue, with no results. My y meter has been faulty since even before 2013. They even had the wrong meter number on my account and asked me where the other meter was!!! How was I supposed to know? I was then told my meter must have turned over maybe even 2x and my account should be much more than the amount it was at the time which was already over R50000. 00. They said it should be almost R279000.00. Fortunately I found emails dating back to 2013/2014 from the head inspector, stating that my meter was faulty and had to be replaced, the photos were attached with the exact same reading on it. I forwarded all the relevant information to the office and had a new meter installed. Still no electricity by the way so obviously no reading on the meter when I went back to the municipality with pictures of the meter I was told they have to replace the meter as thereis no reading!!! How pathetic is that!! I've been about 20 times or more to different municipalities to try resolve this issue but no matter how much I explain and show proof of my meter with zero on it they kept on billing me. Eventually they credited my account with R20000.00 but what about the other 60 or R70000.00. I am so frustrated at this stage because it's a total waste of time going into the office to try resolve this issue. 4 years of being without electricity is no joke! On top of it they charge interest on the amount which is incorrect. I'm at my wit's end!! I would love to get the Mayor's email address!!! Ho do I get this issue resolved?
