Broadband speed has been slow for almost 2 weeks.

Question

I have been getting slow to extremely slow connection speed for almost 2 weeks now. 
 IP Profile for your line is - 9446 Kbps
Download speedachieved during the test was - 3548 Kbps
 For your connection, the acceptable range of speeds is 4000-21000 Kbps.
Just made this test and this is the FASTEST i have ever tested on the connection. Usually its more like 1000-2000kbps
The upload sits around 40-70kbps most of the time which is also extremely slow.
I have tried using 4 different filters. 2 different routers and my computer is directly connected to the router. I had no problems before this and my speed has always been good or great (20000kbps)
I have used a lot of time on the phone with the call center and they keep coming up with useless explanations and excuses for why the connection is slow (I work with this every day myself so i know that they have no clue)
This is my last shot to get a solution to this problem. If not i guess i will have to change service provider since the connection i have now is so bad i cant do anything else than reading stuff on the internet and sometimes watch a youtube video. My internet connection is vital to me since i use it for work so this is very annoying.
So... Does anyone have any idea what i can do?

 Here is all the information i could find for you together with a full test. I have done a factory reset two times without any luck
Test1 comprises of two tests

 Download speedachieved during the test was - 3712 Kbps
 For your connection, the acceptable range of speeds is 4000-21000 Kbps.
 Additional Information:
 Your DSL Connection Rate :10707 Kbps(DOWN-STREAM), 104 Kbps(UP-STREAM)
 IP Profile for your line is - 9446 Kbps
2. Upstream Test:  -provides background information.
