I don’t know what to do with these neighbours?

Everytime we leave the house they will opening the window or looking though out kitchen window then they’ll move there car 100 times to see if we will come out and then today we went to church and my sister parked there near our house but when we came back a white van parked there they make me feel so uncomfortable I can’t even leave the house without seeing there car what should I do ignore them?
