Yeah they wont stop calling me :/ even after i told them that im not interested and i can't donate due to not having much of an income. They call once every month, getting annoying.
After having told them that I've been contributing already, they are still calling me for more. I understand it's a charity and people truly suffer but money does not grow on trees and I have to look after my own well-being too. I will give when I want to, at the amount that I can and am willing to give.
