more than 3 months terrible speed

I have a 2mbps line and have been getting speeds of less than 0.40mbps. I have reported it so many times that I have lost count and every time I do they say it's fixed. I've also noticed that my upload speed is much higher than my download speed. this has been happening ever since the lines went down a few months back. Can someone please explain to me why is this happening and why is it not fixed yet.
