These folks called and left no message. Reverse phone number lookup and low and behold its another telemarketer trying to sell me something I don't want or need.
I get calls from this number occasionally. After doing some searching on the web, I've discovered that the number belongs to a sales agent for eZanga.com. They are a pay-per-click (PPC) and internet marketing company.
I don't know how legit they are and have not called them back. I am guessing they got my number off my business web page and are now trying to sell there services to me.
