How do you respond the canvassing calls from some banks for house loan,car loan etc?

I was getting frequent calls from a particular bank,during my siesta time,explaining about different loan schemes they offered.My repeated requests to them not to make any call didn’t yield any result.One afternoon a girl in her sweet voice started explaining about loans and inquired about my job.I just said.”I am begging in a down town junction from morning to evening”.She said sorry.
I don’t get any call now.
How do you treat these calls?
