poor customer service

I contacted Vodacom ' s cancellation department on the 29th to cancel my current contract and switch to a prepaid package. This request was supposedly processed but I didn't receive the confirmation sms that was promised by the consultant. I called them again on the 30th to confirm the new prepaid contract would kick in on the first and to request the confirmation. When I called the first time, a female consultant picked up but instead of talking to me, she was making her lunch order with a male \colleague"who was going out to buy lunch. She realised I've been holding for too long and she hang up without saying a word. I tried again and got a consultant who confirmed that everything was in order for the first but again I didn't receive the confirmation sms. I realised on the first that I still received the old package and then contacted the cancellation department round about 7:30 am. I spoke to Vuyo who said she'd log a call and that the person who worked on my request would contact me. No one called up until 5:30 PM so I made another call n I spoke to Lebo who repeated Vuyo' s words. It's the 6th today and no one from Vodacom has contacted me. And they still say power to you"""
