I received a call from this number with a 4 at the end. Everyone is asking the same question, How can we get this to stop? Is there a number to call to get my number blocked from future calls? I don't want to start getting harrased. I almost called the number back thinking it might be an emergency. What kind of charge would I have received? Does anyone do retail store survey's? I recently did a Rite Aid and Walmart Survey. Do you think this could be the reason I am being targeted?
