Telkom Incompetant and charging me for service I have no knowledge of

Hello Peter Please assist!!!!!, Telkom has been the worst I have ever dealt with to date, they do not deal with their queries, take instructions from clients, request ect, in January 2018 I app**** for the January deal to which Telkom offered for R499 uncapped including free router, LIT BOX and wi fi extender , about 4 months after application approval Telkom decides to install my system and only supplying the router without the other freebies saying I was not part of the first 5000 customers, but that's not what the lady told me when I had app****, she told me that I will receive all that they had advertised for, I also at the same time confirmed that I the monthly premium will be R499 no more, if I do make use of the telephone making calls to cellphones their would be a charge, but Telkom to Telkom absolutely free of charge, 2 months after they installed and not notified by payments not being made they disconnected my line, I then called the call center and my nightmare began, apparently they were changing me for other services, and they will investigate, no feedback to date, I have all references and correspondence with Telkom, I also called to lodge a complaint regarding my line that it is extremely slow and that I cannot use it, got a ref , got a call form the call center but no resolution to date, today I take a look at my statement/billing and discovered that Telkom is actually charging me for a whole lot of services to which I did not agree and sighn up for,. I called the call center again and spoke to another *********** agent who kept me on hold for most of my call rectifying details to which I rectified on previous calls to Telkom, please assist, Telkom is charging me for services, and not resolving my queries, I don't use my internet because its offline 99% of the time, SO WHAT AM I PAYING FOR AND WHY ARE YOU ROBBING YOUR CLIENTS,????????. I can provide ref numbers upon request
