Telkom force me to pay something I'm not happy about.

I have been a Telkom customers for years,but now the experience that I have received, its very bad, I had two contracts with them and one was already on a month to month which I was happy about it,and received a call telling me that I'm due for an upgrade, I told the consultant that with the month to Month I'm fine I don't want to do the upgrade and he told me he will do it on the other contract, to my surprise he did it on a month to month without my knowledge, and also I did a laptop contract with them and specified that I need a laptop with CD ROM of which I they sent one without the CD ROM.

Now when I cancel these contract the one for the laptop they charge me R5000 which is within 7 days of their period and which is their fault, and still waiting to hear how much they are going to charge me for the other contract that I told them not to charge me.

I'm stuck with two contracts that I don't want,and now they threatened to blacklist me,why should I pay for something that I dont want?

Why should be the fault be on my side?

I'm prepared to reverse whatever money they will deduct from my account from now on going forward.
