INCORRECT EMAIL PROVIDED

I called Telkom on the 10 September 2015 to cancel 8 lines and was given an email address and instructions on which documentation to submit, as per the documentation I submitted the agent knew it was for business but gave me a residential email address and to date I recieved no correspondence and within 5 days it wil be a full month. I called my account manager at telkom today and she told me the address was incorrect and gave the correct address that sent me an automatic response email which states that the 30 day notice period starts from the day the cancellation is recieved and I DO NOT ACCEPT THIS! I was given the incorrect email address on the10 September 2015<br> I also have been paying for an ADSL line for almost a year that I have not been using due to bad service delivery for internet on that line and I moved over to mobile routers with telkom - I need a refund on the rental of this line <br> I called to speak to someone in the cancellation department ealier today and I am told that they only work on emails and this does not work for me
