Account Cancellation

On the 19th of June 2015, I had called the Telkom Call Centre to cancel my telephone line and Adsl package, and close my account. It has been almost two months and I am still being billed. So i decided to go to the store in Fourways Crossing on 14th August 2015, arrived before 9am and waited for the store to open, when i sat down with the consultant and explained my problem to her, and i would like my deposit refunded. She stated that the line was cancelled although you will have to carry on paying until they close the account and credit me for all my excess payments. I then asked how long does that take cause its been almost two months, she said she does not know, it could take up to 6months. I did get annoyed and raised my voice and said this is the worst service i ever got. She went on to say \I cannot take your energy so early in the morning
