Internet still not fixed

Hi, over the last month or 2 I've been having problems on my internet line. The internet speed is running a 0.6mb it's supposed to at least run a 1.7mb seeing as it's a 2mb line. The ping on my internet is above 130 as well. I've reported the fault 3 times already. Every time they let me know that the problem is fixed, but it isn't. I'm a IT student and I rely on the internet to do online quizzes and basically my entire course requires me to have internet. I can't get onto my sites to do my work and this is seriously starting to bug me now. Especially considering how many times I've had to report the problem and sit waiting for hours on the phone to their call centre trying to get through to get the problem tended to. At this moment as I'm typing this message my internet speed is running at half of what is should be and it's a pain just to write this on Hellopeter as it take me forever to get onto the site because of the high ping. Needless to say I'm not impressed.
