Unattended call logged

I have logged a call for a street light that is not working on the 17th April 19 and I was informed it should be sorted within 7 days that's their time frame log number ********** 977. Today it's the 28 May and the light is still not fixed,I have done numerous follow ups and I always get the same message "we will escalate" now whats the point of escalating if nothing happens and from there on you get no info when this will be fixed you ask to speak to someone senior they still tell you they can't do anything except to escalate so basically there is no process in place and no disciplinary,no body cares about us consumers I can call and call and nothing will happen so why do they give us the SLA and why do they advise us to follow up when nothing happens?this is pathetic service and as a service provider something must be done we do not need to take to the streets at all times but someone needs to take accountability for this i am a customer and so I should be treated,these people are useless at first you will have to wait untill they take your call which will take 45 minutes just for a follow up and only to be told that we will escalate.useless,pathetic and utter nonsense City of Tshwane must get their acts together.
