Abusive behavior

Once again Ethekweni have failed to provide us with our electricity account,so being busy at work,I asked my elderly mom to call the call center and gave her our last bill with all our details. She phoned me in tears later that day,someone had taken her call and had been incredibly rude and unkind to her on the phone. When she she had asked him to repeat the amount we owe he had whistled in her ear and asked her if there is something wrong with her,why hadn't she written it down the first time! He was not going to repeat himself! When she asked for his name he told her it's none of her business! I then contacted Ethekweni,apart from constantly struggling to get our account from them since we moved,I can't understand why they employ people who are rude and aggressive when there are so many people looking for jobs. They were able to tell me who she had spoken to and eventually what my account was,although not why we are still not receiving accounts! I would have to speak to another department for that! Par for the course with government departments,no one cares!
