Telkom *****ing my money

So today I went in to telkom again to sort out my cancellation on my contract. Trying to cancel it since December. (Ref: ********** 6) So the reason why I am struggling to cancel my contract is because Telkom made an mistake giving me a 30gb contact instead of a of a 20gb contract. After a few months of going in to Telkom to change it they changed if but they did not want to refund me my money they took. And the way the changed my contract is to cancel my contract and opening a new one without me knowing about it for another 24 months Because they made a mistake. I found out about this when I wanted to cancel my contract December 2017 then they told me my contact did not expire yet. Today I went in to telkom in centurion mall talking to Tshepiso Baloyi and when I told her I wanted to cancel my contract she told me she can not help me with that. So I insisted her to look up the ref number she did not want to so I again explained to her the whole thing getting irritated with her not willing to help she finally looked it up and only told me they are working on it not knowing when they will be done with it. So I explained to her Telkom is costing me more than R3300 so far and she can not help me in any way I asked her so can I cancel my debit order she responded "Its up to me to do what I want to do". Know this is getting to ridicules. And Telkom does not want to sort this out I have Emailed Phoned in and went to the telkom stores and no one is willing to help this is my last option. I am going to cancel my debit order. Maybe then you can sort this out. Not to mention my previous Incident with my other telkom number. You can go read up about it you will be able to find if in your records.
