Telkom charging but not delivering at all

Telkom is *********** and utterly useless. I signed up in March 2018 for a Telkom Fiber deal of R799. I had 3 consultants phoning me all asking me to sign up within one month and nothing happened. I decided end of March to sign up myself via there internet page. I received a sms telling me they will send a technician to install the fiber and that everything is in motion. I waited 4 weeks and nothing! Telkom then decided to start charging me so long for this deal. I was still paying for my ADSL rental at Telkom and paying my third party ISP also while I hadno FIBRE and no uncapped internet from Telkom. I opened a fault and explained in length that I refuse to pay for something I have not received and that I should be credited. This actually happened BUT they only cancelled the Fiber rental and not the Internet. So they sell you a car, drop the engine of at your house and ask you to make the monthly payments while you wait for the rest. They sell deals and deliver nothing, but charge you with half the deal in the meanwhile while your fight with poor Telkom callcentre agents who cannot do anything but to escalate the call! I have logged faults, followed up, The calls have being "escalated" but they never phone back or follow up. I have a escalations on a escalation for my one logged fault already. I want to settle my outstanding balance but it contains 3 months worth of ISP charges I never used. Even if I wanted to can I not because I have not received a login and password from Telkom for me to be able to change my ADSL router. To top everything off does it seem they they now canceled my ADSL line rental now also which I specifically asked not to do. I logged a fault for that also , but I am confident it is going to take months to get that working now. I do a lot of work from home so now I have to use super expensive 3G internet and suffer financial loss because of Telkom's incompetence.
