I used a cell phone number for gmail and featurepoints sign up/verification. somehow the people at the company traced the home phone number

I was completing tap research surveys on featurepoints every day and the person I live with was mad because there were so many unsolicit callers calling the home phone. I think the calls are from agreeing/completing featurepoint/tapresearch surveys and some people from the research firms etc will call the survey completer to offer him or her useful things. and they might contact the survey completer online/email or by visits etc
