Telkom making it impossible to cancel my contract

On the last week of May 2017, I did an online purchase through Telkom website for their R199 BIG DEAL of that month, which included the following: 1. LTE wifi Modem 2. 5GB Telkom Mobile Data 3. 5GB Telkom Night Surfer Data 4. 5GB Day Time Data I was immediately contacted by their agent whom I asked to "clearly" explain the package properly to me, especially the 5GB Telkom Mobile Data. Her explanation was: you will get two sim cards with the Modem, 1 sim is for the 5GB Telkom Mobile Data and the other one was the 10GB of Night and Day time Data. I was happy with the explanation because I wanted to use that 5GB mobile data in my own USB 3G modem and leave the 10GB for home usage as we only home between 6PM and 6AM weekdays due to our work. Then I agreed to apply for the contract. Before I received the contract, they had sent me an sms informing me about their initial charge of R199 to show that I can afford the contract which they did make on the 7th June 2017. The package was then delivered to my workplace on the 9th of June 2017 WITHOUT Telkom contacting me, I had to call them on 12th June 2017 to find where is the package and only to find it was delivered on Friday 9th when I was not in the office and I was not even notified. When I opened, the package I realised that it only had only 1 sim card packaged with the modem and I immediately contacted Telkom again on the 12th June 2017 to find what was going on and I was shocked and surprised that none of the agents I communicated knew nothing about the contract that I was explaining. I cancellation the contract with several agents over the phone and they all kept saying that they will send a dispatch company to come and collect the device, nothing happened and money kept on going out of my account. I then went to Telkom shop in Festival Mall, Kempton Park on the 12th July 2017, where I hoped to be assisted and even they couldn't help me. I was given a cancellation form by gentleman called Tebogo Ramotsepe who tried to also call Telkom and assist but also struggled. I completed the form and sent it to an agent by the name of Yonela Matjila at Telkom whose job Title is Senior Associate. I was then contacted by a lady called Ditoro from Telkom on the 19th July with call ref: ********** 5 who explained the process again and informed me that they will need to get the conversation recordings first and then continue with cancellation. The last week of July 2017 or early August Ditoro called me back and told me that they listened to the recording and their agent DID SAY the package will come with 2 SIM cards that can be used differently, and she apologised for the inconvenience on behalf of Telkom which was wrong of the agent. She even went on to offer an addition certain amount of free data for 12months which I declined, I asked her to cancel my contract and pay me back as I haven't even used the data and the device. She then agreed with me and told me she will forward to cancellation who will continue with refund. End of August they still deducted my money, I called Telkom again in September 13th 2017 and spoke to a lady by the name of Anec Mhlambi who also saw the issues under my reference numbers and she also promised to contact Ditoro and make sure the deduction will not go through. She even sent me her email address to follow up with her. On 15th September 2017, I sent Anec an email to find what is going on, she also never rep****. Came end of September Telkom AGAIN DEBITED MY ACCOUNT. I do not know what to do or where to go anymore because I followed all the correct channels in terms of cancelling the contract but they are just ignoring my issues. I feel that my rights as a customer have been violated and they just dont care. Please, please help.

Kind Regards
