Cannot Cancel my Contracts

About 6 months ago, I decided to start moving my company lines to a competitor network because of appalling service. I went into the local Telkom branch to cancel to contracts. I had to fill out a form requesting the cancellation. Over a month later the call center finally calls me to initiate the cancellation of the contracts. She states that it will cost approximately R14 000 per contract to cancel!!! The contracts had recently been upgraded and I expected the cancellation costs for the hardware to be high. Given the fact that legally Telkom may only ask me for the hardware and a small admin fee, I knew that R14 000 was way out. I asked her to explain and she started by telling me that we had to pay for the subscription fees times the remaining months. This is against the law. When I told her this, she backtracked and said that this was only an estimate and that the correct department would contact me. A MONTH later I received a call, this time quoting me R9000 per contract. I still could not understand this fee and asked for it to be broken down on an email to me. I am still waiting almost 2 months later. All the while paying R1899 x 2 per month for contracts we do not use!!!
