Eskom not taking responsibility for their pathetic customer service consultants while ripping us off!

I wrote a complaint letter to Eskom 3 weeks ago and the automated response said they will respond within 5 day, 2 weeks later I haven't had any response from Eskom instead I called the client services where I spoke to Happiness who was rude and clueless. Happiness hung up on me. My complaint was never resolved up to date I need to call and follow up on Eskom where else they are the one at fault.
