Telkom ****s me

I requested for a fibre contract in Feb 2018 as it was available in my area , after I was told to wait 21 days it was still not installed finally after 1 month it was installed but no internet or landline for 4 weeks, it worked fine but speeds were slow, I had a "home unlimited 10mbs uncapped deal" where I was promised that the fair usage policy was 900gb and i was suppose to receive a free LiT box which i did not till today, on the 21st of August my speed was very slow and I called the technical support, they said my line has been kept as I used 100gb as I'm on a soft cap 100 which is not correct I was on an uncapped 10mb Telekom home fibre package, non of the agents could give me information or help me even though I never had my fibre activated all this time and have been paying all these months, I was transferred from department to department for 3 hours where the consultants were rude and could not help , they also denied me from speaking to a manager , finally my called got answered by someone who understood my situation and logged a request however nothing has been done yet and my internet speed is 200kbs which is 2 percent of the speed I'm paying for , I have been ********** all these months and nothing has been done , I'm fed up of this service and I'm on the vurge of cancelling my contract and taking legal action for this **** because I'm not receiving the service I'm paying for
