Leaving belongings behind at this hotel by mistake is not safe at all

I mistakenly left my jacket at that hotel sometime end of Jan/ early Feb, the following day my boyfriend went there to look for the jacket and they told him he must wait for the supervisor to come in work because she or he is the one that took the jacket. We went to the hotel again the day she was working and they said they can’t see the jacket they will give us a call back when they found it. They then called us saying they found it, we went there and when we got there they said they don’t see where they placed the jacket again. Now it’s March since they said they will call me back to ask me how much the jacket cost me so they can replace it, they never called me till today. I spoke to the receptionist called Lebogang, I didn’t get the supervisor’s name…so they literally took my jacket and now won’t give it back
