Absolutely no response whatsoever

I sent in an assignment about a month ago and haven't received any feedback whatsoever, even after emailing them on a bunch of different email addresses- no reason why it should take this long without infroming the student. Now i have to pay for the entire month but I couldn't study further because they don't send your next work before you get marks back.<br> Also I don't know what is going on in their accounts since I have to pay for an entire month of Feb when I was only a registered on the 22nd of Feb , after being told my first payment would only be in March. <br> I did fill in 2 \red alert\" forms where they are suppose to contact you immediately AND STILL DIDN'T GET A REPLY.
