Beyond poor service from City Powers

I have a big problem with city powers contractors that are BIG *****. The contractor Ansley's team was in our street three weeks and said they will come and sort it out. My reference number has been updated and allocated to Ansley but until today we are still in the dark since March 2021. I was checking up every week on to hear about the update and Ansley said to me on the 11 August 2021 to get him a new reference number because the previous reference number has been closed and according to my knowledge only the contractor can close the reference number which it was assigned to. Till to date Ansley does not answers my call or responds to my messages. Our last communication was the 12 August 2021 which he told me that they sourcing the material up until now. The team leader was in our street to assess our street light situation and said that they will approve it. Our street is dark since March 2021 and people are getting ******, hijacked and hurt. I have a question for CITY POWERS? Should we stop paying rates and taxes because we not getting service delivery from you guys or should we take matters in our own hands and shame you guys?
