Call Centre Lies to get you to take the upgrade

I have been on hold at Telkom for 45min, just to be told, they cant assist me. I am trying to get the recording of when I upgraded. I asked 6 times if he was sure that no additional charges will be billed, and he promised me, there is none. He even said, I can use my new contract and I will not be paying for it. I get my bill yesterday, and I was charged pro rata for the contract and I was charged twice for the added on device. My bill is R800 more than what it should be. I cant get through to the people who hold on to the recordings, yet every call you make or receive, they are quick to say, all calls are recorded. <br> <br> I want my recording, as I demand a refund for this. <br>
