Disgusting service

I subscribed to LTE with Telkom. On 7 December 2017 I called into the Garden Route Mall to cancel the service and was given reference no ********** 3. Nothing happened and I called in early January to be told that I must wait until 8 Jan for it to be acted on. Nothing happened. On 16 Jan (ref no ********** 06) I called again and was told that nothing had been done. They promised to escalate it and would speak to cancellations. I emailed a further advice to cancellations. Nothing happened. I then called in Garden Route Mall Telkom office again on 12 February (case no ********** 2) and submitted the documentation again. I got confirmation on 14 Feb that my query had been resolved. I then received a further invoice from Telkom indicating that I owed them R725.00 with a further R598 due to be presented on 1 March. I phoned again and was told that nothing had been done but the supervisor would follow up Her name was Luthando who promised to send me her email address for me to follow up. Needless to say the email never arrived. I then phoned on 7 March and spoke to somebody who did not know who Luthando was and said I could not speak to a supervisor as they were in a meeting but I must phone bac****!! I then did so and spoke to Masilo and held on for half an hour and she said that I would be called back within the hour. Six hours later I am still waiting. I then tried your online chat only to be told Telkom systems are slow and they could not help me and I must phone back. Quite pathetic service as they will have listed the account on credit bureau saying that they were owed money. Amazingly the facility was finally cancelled on 15 February but despite my complaint they still say I owe R725.00. I am not a contract customer and this should have been cancelled in December.
