To complain about fundraisers knocking on my door at night

I never usually open the door at night but as I was expecting a visitor when there was a knock on the front door I did open it and was very surprised and extremely annoyed to find a young woman campaigning for funds on behalf of Battersea Dogs and Cats Home. She was polite so no problem there but I personally have a problem with the timing and told her so in no uncertain terms.

I do not think that anyone should be knocking on doors at night campaigning for funds and I was shocked that BDCH has allowed this to happen especially given the negative publicity that charities have received recently regarding their fundraising activities. I have complained to BDCH and await their response.

What do you think?
