Rustenburg Local Municipality is past pathetic

I have been struggling for 3 years to get an account e-mailed to my new e-mail address. The few times the phone was actually answered (I made more than 70 attempts to get in contact with them - even sent e-mails), I was placed on hold for hours on end. Despite the fact that I have not received a statement in 3 years, I kept on paying my account based on assumptions made of how much I owed. I received an "overdue" final demand letter from the municipality to the amount of R32000 on Friday. Upon investigation, I found that the meter number for my unit does not correspond to the meter number on their final demand letter. I have made in excess of 30 calls to the various number I could find and the numbers displayed on the letter of demand - with no success of reaching a single individual. IS THERE ANYONE OUT THERE WHO CAN PROVIDE ME WITH A CONTACT NUMBER that is manned by a person willing to assist?
