Requested hours are not respected - Retail Sales Associate T.K. Maxx Employee Review

I was a full-time university student, something I made clear during interviews, I was on an 8-hour contract, and I made clear that due to being a young carer and in university, I couldn't work more than 15 hours a week, but was regularly scheduled at 25+hrs. I made several complaints to the managers, had to get my shifts covered, and eventually ended up quitting as nothing changed. Oh, and the manager would often cheat on his wife and sleep with the young girls on the shop floor.
