Worst customer service by Eskom!!!

Wow! I've had some bad experiences with call centres but Eskom takes the cake! Firstly I've waited 1 whole hour to get through to a representative. I asked her how many reps are actually working at the call centre and she has the nerve to tell me that she's the only 1 working whilst everyone is getting ready to go home (time was 15:50). I queried the inconsistent invoices I've received for the past 3 months due to Eskom taking estimate readings on consumption, from 44kW to 8kW to wait for it.... A whopping 688kW!!! The rep couldn't explain it and said that I just need to pay it otherwise they will disconnect my service. I moved house in Feb, it only took Eskom until Sept to successfully transfer the account into my name. I asked if the account should be put on hold whilst they investigate the account, she ended up just giving me a reference number without answering my question. Once the reference number was given it went to pure silence... This is when I realized that its 16:02 and she probably muted my call thinking that I was going to end it so she can finally knock off from work... Little did she know that I would just keep the call going until she ended the call from her side at 16:05. By far the worst customer experience encountered and my query is still unresolved... In my past experience working in call centres this type of behaviour on a call would end up in a hearing and most likely a dismissal. But its Eskom after all... Their employees can probably get away with anything with the state that the company is in at the moment.
