Complaint from a very upset person

I was called to do an upgrade with Telkom not that I needed it but since they called me I did it telephonically. I now need to know how far my order is and called 10213 only to hold on the line for over 20 minutes and had to call back again to hold even longer and when I eventually got through to someone named Ntokozo Mkhize I was told sorry wrong line call back to the same number. I asked to be transferred and was told we cannot but that I must call back. I have never experienced such humiliation from a customer service consultant in my life. When asked to speak to the supervisor I was told she's busy. I don't think you will be getting a renewal from me anymore.
