Telkom no service in all aspects of the word!!!!!!!!!!!

In February this year I decided to take out an ADSL contract from Telkom, after installation it became clear that the package I took (5mb/s uncapped) where very slow and I could only access small emails, Facebook & WhatsApp , I made contact with Telkom to get a bigger line and requested the 10mb/s Uncapped package they agreed and I upgraded after 2 weeks with no reply I inquired and where told that the area I stayed in does not support my request so they cancelled the request without informing me. Needless to say upset that they did not even bother to notify me I requested what is available within my area and they advised that I could go to an 8mb/s line I agreed and waited another 2 weeks for this to happen. After the migration the service remained slow with barely any difference, I decided to go into the Telkom store in Canal Walk, to address the matter I logged the calls and they where to get back to me after another 2 weeks I returned as nothing where done only after a heated discussion they advised that I need to take their test LTE unit to see if it might work as the adsl clearly does not, I had to purchase data to test the unit. I returned home and did a speed test on the asdl and send it to them via email and did the same with the LTE, they clearly saw that the adsl line where running way to slow and that I will never have the service I require/ed they then advised that I cancelled the adsl line and move to the LTE on which I agreed. They provided me with the cancellation forms and I completed and submitted it to them via email (I have all documentation and correspondence on record) again 2 weeks no joy I returned to the stare and insisted to talk with the manager Wayne Reyneke, again had to go through the entire story, after this he promised to get back to me himself within 2 days.... not really to my surprise his consultant contacted me a week later and stating that they submitted the cancellation. Again nothing... after desperately trying to resolve in store with numerous visits I contacted the call center just to be advised that they received no cancellation from Telkom Canal Walk. And off to Telkom Canal I went .... Again, this time a new consultant and without surprise the Manager Wayne Reyneke not available, by having enough and another heated discussion the cancellation where done from the store. So a couple of days later I received a call from Telkom stating I owe them set amount, I queried the amount as I have been charged for a service I did not receive, they credited the amount and I paid the balance. Again another call from Telkom stating that they will cancel the contract but I will need to pay the cancellation fee.... I what world will I or anyone do just that. I pay for a service I don't receive, then on agreement and advi*****t from them I need to cancel the contract just to be responsible for a cancellation fee.... OVER MY DEAD BODY! I need this to be resolved they can cancel this and we can go our different ways I will never in my live deal with them again nor will anyone I know as I will ensure they all know what I went through!
