CANCALLING MY TELKOM CONTRACT AND CONVERTING MY NUMBERS TO PREPAID

I had 3 devices on contract with Telkom. My first contract ended in April 2018 and since then I have struggled to get my contracts cancelled and my numbers converted to prepaid. On the 1st of March 2018, I sent an email to the cancellation email requesting a cancellation form to complete. NO RESPONDS. I spoke to Customer service representative Nontokozo Jula ********** on 10th March 2018 regarding cancelling my contract. I completed the form as per instructed. NOTHING HAPPENED. I NEVER RECEIVED AN CANCALLATION SMS/EMAIL. On the 12th March 2018, I sent another email asking to convert to my cell numbers to prepaid asap together with my cancellation form. NO RESPONDS. On 4th April 2018 I sent an email asking when will my contract will cancel and my number converted - NO RESPONDS. I attempted to cancel my contract again on 29 May 2018 and I spoke to "Dikeledi Paulina Nodali (D)" ********** regarding my cancelling my contract. NOTHING HAPPENED. I NEVER RECEIVED AN CANCALLATION SMS/EMAIL. I attempted to cancel my contract again on 19 July 2018 and spoke to Misheil Bongiwe Dladla (MB)" ********** To this day I have not received a call from Telkom regarding converting my contract to prepaid. Yet I get calls from Telkom wanting to sell my stuff, but No one can help me to cancel my contract. I am really livid and want this sorted asap.
