Received a call from this number, but did not recognize the number and did not answer. No message. I believe these people call and call, looking for victims of their "survey." I did answer once last month, but hung up on them when they asked me if I would mind answering some of their questions. I know this is redundant but never give out any information over the phone! Especially to unknown callers. Most likely, if there is no return company name, call back, etc. it is probably a scam. Safety first!
