No service, no feedback, keep on waiting

I can't even begin to describe my disappointment about my experience with Damelin Correspondence College. I enrolled last year June, and ever since I had to phone time and time again to follow up on my assignment marks. And I also have queries about certain subjects. And when I finally get through to a consultant, it is the same story every time: We will send an e-mail, we will phone you, and we will e-mail you. At this rate, I don't know how I will finish in time. How should I know what to do if no one gets back to me? With my previous complaint here, a consultant phoned me back and I did receive my assignment marks, but if it means I have to log a complaint each time to get feedback, it is not working for me. So either Damelin starts getting back to me (Correspondence College? I think not!), or I am cancelling my course and asking for a refund. Because I phoned again yesterday, and was told they will phone me back the same day or earlier today. I am still waiting and it is 14:00. I even sent an e-mail this morning to follow up, and still no e-mail or phone call. I am really so tired of struggling to get any feedback. How should one study with these circumstances?
