No cancellation of services

On 9 July 2015 I sent Telkom an email (after I was instructed to do so during my 1h13min phone call with their call cntr) requesting the cancellation of 1 of my telephone lines. Today, 8 September 2015 I received my new invoice and am STILL being invoiced for this line. After spending almost 3 hours on the line to speak to a Telkom member that can assist I was yet again provided with another email address to send the request for cancellation to. I guess I should just wait for the legal department to call me now as I am making no further payments to Telkom for the other lines I have and should they suspend my services I will simply get NEOTEL to provide me with services. After all, they actually deliver when it matters most.
