Battle to have Telkom LTE account closed

Why am I not surprised that this happens again. (Same problem 2 years back) This time round I had a LTE contract for two years. I tried online (even with their assistance in their shop) and with multiple calls to have the account closed. No joy!!! I went to their Lakeside Mall branch and filed in a “Consumer Request for Contract and Service Cancellation”. This was done more than the expected 30 days’ notice to have the account closed. On expiry date I removed their equipment to ensure there is no breach from my side. I kept on monitoring the account and see that it is not being closed. I followed up with a SMS to their 081180 number. Still no joy!!! Surprise this morning. Debit Order of R1309.12 was deducted from my account. For what??? No Service, Bad admin, Account closure system that does not work!
