Worst service ever

I chatted with TOBI Vodacoms chat bot on Sunday and requested a human consultant to phone me back. First lady, Nonhle, couldn't resolve my query. That was around 10 in the morning. The second one, Thabile, spoke to me around half past one in the afternoon. My query was still not resolved. The third one, Lydia was extremely rude to me. When I asked her if I could speak to her manager regarding her attitude and behaviour towards me, she started to scream at me. How can you treat a client like this?? That happened around 2 in the afternoon. Apparently the phone calls gets recorded to ensure quality of service so there should be proof of this incident. This is the worst service that I have ever received from a network operator. I'm very shocked to say the least as this is the very first time that this has happened. Something in general besides the above mentioned : please ensure that the operators doesn't interrupt the clients while they are talking. I had that problem ever since I phoned in to your customer service department. Lydia seems to have a huge problem doing that as she was the worst of them all. If this is the kind of treatment that I can expect from a massive service provider as yourself, then I am going to make arrangements to change networks. Please let me know what arrangements you are going to make to ensure that this issue will be resolved ASAP, and that this will never happen again.
