Erm.. What could possibly take 2 weeks to fix on a speed issue?
Want Mr. SaintK to write a letter again? =)
We have this thing called a 'Telemeter' which measures the amount of data you have downloaded. If you exceed a certain limit you get an ultra-slow connection. Somehow my cap was reached way too fast. Normally it resets every month, and normally that is at the beginning of the month. So I downloaded a tad more at the end of the month thinking it would reset shortly afterwards. My meter filled up rapidly and now I get a notice that the next reset is now set at the 17th of July.

Oooooh ofcource your Belgium, i forgot about that!
When are you going to change ISP's? Because there currently is a bandwidth limit revolution going on in Belgium, if i were u i'd change ISP's!
