The reason large companies often call using these numbers that are 'blocked' are often just simply company policies and are done for safety reasons to the employees. I have experienced this in my own line of work and there have been cases were some crazy customers have treatened individuals calling them. So in order to ensure the safety of their employees companies block their numbers. They are not 'pranking' or 'scamming' they just have to do it as a safety measure.
O.K. first off without being to rude lets clarify something. Your identity CANNOT be stolen by simply answering the phone. I understand that people are concerned because there are plenty of scams out there but that is just dumb. People get scammed because they give out personal info. Second, Market Research 101 says never to leave voicemails. Their objective is to get completes...It is a business. It would make no sense to leave voicemails and let people know who they are. They want to catch you off gaurd so you will take the survey and not have time to develop bias. Last but not least honestly who buys hondas anyway... buy American.
Who's buys honda's? People who like to have cars that hold their value. Not like ur average American piece of junk after 3 years is worth less then u owe on it. That's who. Just purchased 2011 Acura TL sh-awd w/tech package. Not any American made that even comes close. I wish Americans made good cars...I would by them. But the sad truth is...overall...they don't.
