Telkom billing for Contract SIM that isn't working

I took out a 10GB data contract from Telkom, but it is never working. I logged a call in December, and when they couldn't help me, they told me they need to escalate it and it will take a couple of weeks for them to get back to me. I never heard back. 5 February I call again. I log a new call, again they couldn't help me, they told me they need to escalate it and it will take a couple of weeks for them to get back to me. This time they give me a ***. On the 7th someone calls me and says someone will come out to me to take a look. The next day the guy calls me, asks me a couple of questions, and then tells me he is not coming out to me because he can't help me. And I never heard back from Telkom again. I have tried calling Telkom many times, but the call always \drops\" when I get put on hold or they \"can't\" transfer me to the people working on my case. I now have had to buy a Vodacom SIM with prepaid data and have to swap sims in my device every time I need to connect to be able to work. And that after I pay Telkom hundreds every month for a service that I am not getting. Will you guys cancel my contract and refund me my money? Or how do we proceed from here???"
