Very Bad service

My power has been out since 9 pm on 14 May, I logged a call on 15 May at 11:16. I also spoke to the Area manager, and the DA ward manager and followed up till about 12 30 am on 16 June. This morning I received an SMS that my call have been resolved which was incorrect. I tried to escalate and got a response the call is to old and I had to log a new call. This indicates that there system is not working and they do not care about customer service as there is no one else you can escalate to neither are you able to change service provider as they have monopoly
