I manage a restaurant. They call here and ask for Craig because that is the name of the restaurant, I explain he doesn't work here and asked to speak to any owner. I said the owner doesn't work here and I'm the manager and just as quickly she hangs up on me. The rudest thing a telemarketer can do hang up on you when they are bugging you. Of course they didn't identify themselves, I got the info when I called back the # on caller id. Also call this # and have them remove you 888-548-4255 I was actually able to reach someone and asked to be removed. I found this # by going searching for the company and going to contact us page. obviously they don't have anyone to answer the other line. get creative :)
