Still being charged for a dysfunctional line

Dear Telkom<br> Firstly I paid for a 4MB Line and did not once ever see it go over 1.95MB, that is false advertising right there!<br> My internet kept on crashing and we had to call in to get it reconnected numerous times.<br> Towards the end of January it went off about 10 times and after it being off for more then 3 days in a row I said I had enough! I received a call from a lady saying I am overdue with my account, I asked how is this possible as I have a debit order? I then explained my scenario of internet being on and off and said I wish to cancel this nonsense and she understood what I was going through, she then said to call Telkom to confirm it is cancelled a few days later which I did, I tried numerous times with witness at work that stood by my phone while I was with clients as I was on hold each time for over 30MINUTES!!! I see now I have a debit order that went off again! I called in now only to be told to transfer to cancellations and then they will credit me, I have been on hold AGAIN for OVER 30MINUTES!!! This is absolutely unacceptable and I want it sorted out immediately, you can check your system no internet usage since the 25th January when it stopped working completely.
