Outstanding balance

I was called by a rude consultant saying I owe R1200. She could not tell me for what. I asked her what the cancelation fee was and she was unable to assist. I refuse to pay the cancelation fee because I was forced to cancel as my line could not be reconnected to where I was moving to. No one told me that there was going to be further charges. I refuse to pay the cancelation fee. Contact me to sort this out
