slow connection and over charging for their incometence

This has issue has been around since I received the uncapped line whereby I continuously get disconnected due to poor signal or when downloading updates. This gets worse when there is more than 1 person connected to the network. Also when downloading, the download speed has never gone above 250kbs when it should be around 4 MB/s which I have ordered a 4mb/s uncapped line. I took this package at the beginning of January 2018 which was meant to come with a Lit box, wifi extender and a 1gb smart data sim which how I had to collect weeks after I had the line installed and last month (May 25) I was disconnected and when I inquired why I was disconnected I got told that I had to pay for the Lit box, wifi extender and the sim but it was meant to be part of the package that I ordered, now I am being charged R260.21 for them to reconnect my line. I feel that is a breach of contract as telkom has not done it's job correctly and I will not pay for the reconnection for their incompetence. secondly Telkom needs to solve this issue whereby I keep getting disconnected and to up the browsing above 2mb/s otherwise I demand that I pay for a 2mb line then rather than a 4mb line.
