Affiliate Marketing Secrets

Hi,
I used to work for a non-profit that was affiliated with the water district of my local county. My job was to go door to door asking the people im the list to fill out a survey. We were told that we had to fill a certain number of surveys per day. Recently I was fired because they called some people and they claim they never took a survey. I admit that I did falsify some of the answers to meet my daily goal, but not very often. My question is, can I be sued for fraud by the non profit I worked with, the water district, or the people whose surveys were forged? They were not asked to sign anything or show id when they took the survey. They were on the list because they are registered voters. Ive learned my lesson but im hoping getting fired is the only consequence.
Thanks!
