Misplaced or lost assignments as no results received

I submitted my assignment and didn't get my results in over 3 months. Yet before it took a month to receive. Each time that I query it.. The tutorial dept will get back to you but they never do. According to their website.. It takes 22 days to give results and another month to receive the marked assignment back. This time it takes over 3 months. Pathetic services. I'm not sure if they lost it and I'm not redoing my assignments again as it took lots of time to do it.
