Telkom deducts money from my account even though i have cancelled the service

On 23/07/2017 I went to Telkom Westgate to cancel my subscription (SmartPlan 100 Deal for number ********** 368, REF: ********** 329) with them and I was advised that it will be done that month. To my surprise I am still getting invoices and money is still getting deducted from my account for data that I am not even using. I feel aggrieved And cheated by Telkom. I called the call centre on 24 November 2017 and spoke to Lebo who was not so nice. I asked her why the company is still deducting from my side and she said it doesn’t reflect on their system that I requested the service to be cancelled. I asked her to request that the company must not continue to deduct money from my account whilst I go look for the proof and she said I must send the proof first. She was not willing to help, if a client calls and says that the company has been deducting money for services that were cancelled I (if I was a call centre agent) would escalate the issue to my manager or to someone who can investigate this but she chose to not be helpful. I also asked her to send me a copy of the cancellation form so that should I not find the proof I can fill out the form and send it back to them for cancellation and again she did not bother even though she promised that she will do it. Her service was despicable and disgusting. She did not even bother to give me the email address that I should send the proof to. I am contemplating leaving Telkom because of their *********** staff and their rudeness. Instead of being assisted I was asked to go and look for proof and that was time consuming on my part. I had to cancel my plans to go look for a document that they have the original copy of at the branch. Had she requested that the matter be investigated perhaps their investigation team would have found the proof at the branch…that is if they are competent. I propose that they repay me the full amount for the months that they were not supposed to deduct the amount. They must incur the bank charges(or whatever extra charge) not me. I want my full refund. I also want to be contacted by Lebo from the call centre to apologise for being rude and unhelpful and acknowledge the steps she could have taken to try to resolve the matter. I want Telkom to investigate what had happened, was it because the lady at the Westgate branch did not process the forms? I want to be called by a manager to say they have investigated and what the outcome of the investigation is. I feel as though I deserve a complementary free data, a free cellphone or for them to write off my account for their mess. They have been deducting money from my account for nothing when I have been in financial constraints. I could have used that money for something else. This has been emotionally straining because of my financial situation. These companies take advantage of people thinking they wont notice when they deduct their hard earned money.
