Even if you say No Thanks your information are in the requested blocks and in their mind, it's okay to call you. Be sure to take out your info.from the blocks because it can also be sold to a 3rd party. Also, if you act ugly on the phone because of the calls, Do you really think they are going to stand for that. When you mif (Mad,Irritate,Frustrate) these callers, they will go out of their way to tinkle in your cheerios!
