Vodacome Bad customer service

I phoned Vodacom today at 9.02 to upgrade my phone, only to get a consultant that did not want to listen to me and when I tried to talk he kept interrupting me, when I got upset about the constant interruptions he then blamed me for shouting, how can Vodacom, still be in business with Such bad customer service.. not i will not upgrade the phone but will rather cancel my contracts .. John Hwandi, you need to go for customer training I hope your company pull the call and holds you accountable for looing my business .. my calls are recorded thanks to true caller, this will not end here I will be sending this recording to your Executive directors for their opinion on how you handled the call .. constant interruptions by you is not the way you deal with customers and then balm the customer for getting upset
