3 Weeks later and my ADSL line still not fixed

So i recently relocated. I started the line transfer before i moved as i understand it can take a while. So after a hiccup with the line installation i noticed the line was only syncing at 3.1mbps. I called in and i was told that it will be logged, the next day i received an sms saying that the issue was resolved but there was no one at my house. So i rep**** to the sms saying no and phoned in and was told it was escalated . Then the week after that i noticed my line sync speed dropped to 2mbps. So i phoned in again and was notified it was escalated. So today i noticed that my internet was slower again and when i checked my line speed is only 1.4mbps. I am paying for a 4mbps line. Before i moved i even used the adsl checker and was told that this area has 8mbps copper. Now im barely getting 2mbps and no feed back from telkom and no technician? Please i need my internet up and running to the speed i am paying for.
