Telkom: Disgusting and despicable service

I have been trying to get in contact with Telkom with regards to the deposit I paid when I first had my landline installed back in mid 2000's. I have not heard anything from the billing department even though I was assured that the billing dept will look into this. I had an ADSL line that had no voice since last year and this year the ADSL was rather bad as I was getting 2mb on a good day on average. When I requested a cancellation before the 30 day noticed I was denied this request and rather forced to migrate to one of their other products. I this case I think its fair that we just part ways as Telkom is no longer able to offer me service on the same basis that I have. Since my adsl performance is so poor I only think its fair that I can part ways early. I was trying to determine will when I was billed for at the end of May. As I do not have a landline contacting Telkom is difficult to put it mildly. Despite numerous attempts my Twitter DMs and messages has gone unanswered. I have given Telkom no stars but I think, they deserve no stars. I will never do business with Telkom again and will boycott them as their service leaves much to be desired of and the treatment of customers is phenomenally pathetic and *******.
