Poor MBA supervision beyond measure

Doing my MBA with them, since stuck at research proposal. I have submitted over 20 times making changes as they indicated that I need to do but when it returns its something else again. Its been 3 years full that I am going back and forth with no luck. Even appointed someone with PhD to help but lost faith when they returned after his inputs. If I had a choice I would move and go do my dissertation somewhere else. The priority its just money if you paid the service become poor to the level of pain. I registered with it on the basis of price that it was lower than others but the emotional pain, stress and poor service its worse. If you have money go to reputable institutions.
