Faulty line for over a month now, still not fixed

I've logged my very first fault with Telkom on the 28th June and after an escalation and 2 more logged faults my ADSL is still not fixed. From an intermittence line to issues with the exchange server on Telkom's side back to a faulty line, they still can't resolve my issue. I've replaced the ADSL router and still no luck. I've got the 10Mbps 50GB package and for the month I only used 4.67GB so not even 10% of my bundle. So basically I paid for something I can't use and I had no feedback since I logged another fault, 653CTK210715 on the 27th July. I now I must rate my experience with them!? Seriously??? Since they can't keep their part of the contract, I am strongly thinking about cancelling my contract if this is not resolved before the weekend. We need to keep on paying the bill but they don't care about you as a customer. This is the worst service I've ever received from Telkom and is highly disappointed because I've always tried to back Telkom as a good company but they are letting me down.
