Hey Mera. To be honest I don't really understand the problem. I took one pamphlet off them once and it took 3 times of me saying that I am not interested and shutting the door on them to get rid of them. Of course I felt guilty and thought they were just lovely girls. But they are misguided. If their religion has an appeal to you then keep talking to them. If not just rip the band-aid off and grow some balls. They will live. There's no way to keep them happy. Just say you don't want to see them again and shut the door. They won't persist for long. No great soul soothing explanation is required for them.
