Telkom does not even know what services I pay for

I have tried several times to find out what is happening on my account as I am now getting different stories about 4mb uncapped and 10mb capped at 50gb. People phone me but cannot give me an answer what am I going to be billed for, what services do I have.... and then they just place me on hold at work for a long time. I tried phoning, mailing, complaints., to no avail. I want to cancel my service with Telkom and not incur any penalties as this is a Telkom lack of service issue...and no one at Telkom is competent enough to help me! Then a lady phoned and told me that I am on a 10mb line but she doesn't know what I will pay and gave me an amount of R694 although they advertise the same service for R584. But she does not know what package I am on but that I have been upgraded, but don't know what I will pay? Then she just very impolitely told me to phone the call centre again because she doesn't know. The call centre you hold for hours and never get through! So again what is a person to do. If I don't receive a service I want to cancel because I don't get service or even know on what package I am or what to expect to pay?
