BAD,BAD,DISGUSTING ,TERRIBLE SERVICE YERRR.....

I am a student at Regent business school and the service is disgusting.I did not get my first year results in time and had to request and beg until i eventually got them.Then i requested an invoice for the 2nd year fees,they actually sent me a cash plan invoice,when i clearly indicated that i will on Plan C(PAYMENT FOR 9 CONSECUTIVE MONTHS).Now i submitted a Stats Assignment that they sent me,suddenly its wrong and they are threatening to give me a zero mark,yet its their fault.They resent the correct one and they are telling me that if i do not submit by the 18th then i will fail and wont qualify for the exams.Who gives them the right to pressure me as this is their carelessness? Actually i shouldn't be re-doing this assignment as they are the one's in the wrong,they should actually mark the one i submitted.So i would not encourage anyone to register here.All they care about is their money.BAD BAD SERVICE,TERRIBLE,DISGUSTING...
