I also dislike the autimated robo calls that always come during dinner time 🙁 We have learned to shut off the phone during that time.
As far as people calling on the phone for money, if I have to say no to them I politely tell them we aren’t able to help them, thank you for calling and then I hang up. Very often they are still trying to get me to give to them but they are trained that as long as they got someone on the phone they should try to still ask for money, or less money, or can we send you an envelope. I feel bad for these people as it is a very hard job, but we can’t afford to give to everyone.
