wow why don't you call the police ? i don't understand that well

anyway that person is &%$## maybe you have to call a yakuza , sorry i'm running my imaginations ;.;

but i don't know how to help you because as you said they doing on purpose

if that situation is keeping going or meanwhile is resolving try to see a medic to prescribe something to sleep and not give her the satisfaction to see you agitated or disturbed , and you finally have a good repose
