Telkom wifi issues and bad service

<p>My gf and I signed a contract with Telkom in May 2016 for a 4mbs line to be put in my flat, when I asked them if this will be possible they said no problem and I went ahead with the 24 month contract because it included a free modem and free installation (sounded like a great deal at the time) they installed it a few days later but then the problems started, I was now paying R820pm for a 4mbs line however through my ethernet it only picked up 1.5mbs or even less sometimes, my wifi was even worse, it pushed out 0.3 mbs. I called them numerous times to complain and eventually they sent a technician he then said the modem doesn't work I then took it back to get a new one but the problem was the same. I have logged numerous calls at my expense I even told them to take it back and cancel the contract but they refused and said that I will have to pay the contract in full and pay a penalty fee WHICH IS INSANE!!! I am now paying for something I can't even use. I need help. The number which is giving problems is ********** under Tarren Jacobs </p>
