Cancelation of service

I requested cancelation of service on the 17 Feb 2018 for my landline. To date the request has not been actioned and my bank account gets debited for the monthly premiums. I was informed by an attendant at the Mall of Africa branch to request cancelation online - not much help online to do this. She also said I must forward the email I had sent for cancelation to her so she can forward to her manager to follow up !!! It seems like you in a never ending trap with Telkom - they quick to sign you up, but refuse to cancel you. it's a nightmare to try and get hold of them on the phone as you wait forever and then transferred from one department to another without resolution.
