Cancelled line in January and still being charged 8 months later

<p>On 11 January I sent an email along with all required documents (Cancellation request, copy of ID and copy of account with account number) requesting my Telkom line be cancelled immediately. I received an automatic email notifying me that someone may be in touch, but that my line would be cancelled within 20 days of receiving the request. 8 months later, roughly 5 calls, and 3 emails later, I am still being charged for this line. Besides being told that it would be escalated, I am still being charged for this line. I want the line cancelled immediately, and want to be refunded for the 7 months you've continued to charge me despite my explicit instruction to CANCEL MY LINE!</p>
