Bollocks!

I've just received my annual student loan statement and I've discovered that, despite my paying it off through a chunk of my monthly wages, the interest for the last couple of years outweighs the amount I've paid off. So I now actually owe more than when I left Uni. How is that fair or possible?

On the upside, it seems that I'm now finally paying off more than the interest so I will eventually pay it off. But it still isnt fair!
