CANCELLATION ****!!

An agent coerced me into taking a new contract despite already having a product with Telkom and he was so offended that I wasn't willing to go through the process and phone call even though he was saving me R5 a month and giving more data bundles. I took the contract with the understanding that the existing one would be cancelled upon activation of the new one - three months later I am still paying for both and they have asked to log a cancellation. If cancellation is without a 30 day notice you are liable for a fee - I gave verbal notice to the agent in DECEMBER already! I want a refund of the past three months where I paid for a service I was informed would be cancelled.
