9 months to resolve a query

On May 2017 I raised a billing complaint with the CoT. According to the city my account was R134 000 in errears for water and electricity which have been accumulating since April 2014. In an effort to get to the bottom of the issue I requested info to understand the cause and why the city had not flagged the issue. It transpired that the tenant who had been occupying the flat had not been paying the bill since 2014. In order to resolve the matter the city has taken 9 months and counting to provide the information I had requested because I believe there's a case of unfairness and human rights violation. Hope to hear from the city and hopefully this time with a reasonable account on why it has allowed the electricity & water bill to reach this exorbitant amount. It's far easier to collect debt in the early days instead of 3 years later.
