Charity collections at home

Last night we had a charity collector knock at the door at 9.15. He explained he was collecting for tear fund. I explained that this was not an appropriate time and he left. I think that this is a worrying trend that has recently started happening. In the last two weeks we have had four different charity collectors call, all at night.My wife has stated that if she was in the house on her own she would feel threatened by this unnoticed visit. Im sure the elderly or vulnerable would also feel the same.

Has anyone else had similar experiences? I am obviously not against giving to charity but this means of collection I feel is totally inappropriate
