Telkom failed to end 24 months contract

Good Day, My Telkom contract was due to expire after 24 months on April 29,2018. I am referring to the expiry of 24 months contract on 2 devices with numbers ********** 009 and ********** 780. The following steps were taken: 1. Chain of emails was sent to ********** regarding ********** 009 number with requirement to keep the number as pre-paid. Emails were sent on March 19, March 23, March 27. 2. Chain of emails was sent to ********** regarding ********** 780 number with no response from Telkom. Emails were sent on March 19, March 23, March 27, April 4, April 11. 3. Response on ********** 009 number cancellation was received on April 4, 2018. 4. I called Telkom at the beginning of April and was advised to wait. 5. May 1, 2018 - Telkom failed to do cancellation and loaded data on both numbers. 6. May 2, 2018 - I called Telkom. I was advised to send all my communications to ********** who will deal with this issue. Email was sent immediately with the following proof:original contract signed on April 29, 2016; chain of emails to ********** regarding ********** 009 number with requirement to keep the number as pre-paid; response from Telkom on ********** 009 number cancellation (received on April 4); chain of emails to ********** regarding ********** 780 number with no response from Telkom; original cancellation form for ********** 009 which was attached to the original cancellation email and all follow up emails; original cancellation form for ********** 780 which was attached to the original cancellation email and all follow up emails; ID document which was attached to both original cancellation emails and all follow up emails. As you can see there is more than enough evidence to prove that Telkom Cancellations Department failed to deliver the service and breached my contract. In addition to this fact your customer service employee provided me with invalid email address. I need this matter to be sorted immediately before I proceed with legal actions.
