keeps calling 2 -3 times a day.  never leaves a message

They continue call me. Havent answered yet. I read on another forum that is is Direct Media Advertising but I do not know how true that is.

I got a call today from someone from this number.  I could hear a voice though, but they didn't call back. Strange.

Just got a call from this number claiming to be from "Shopping Essentials". They called to let me know I was already qualified to receive a $25 Walmart giftcard. The lady had a very thick accent and informed me that I would receive the giftcard because I made a recent purchase either through the mail or internet but couldnt tell me where it was from. She "just needed to verify some information" which seemed very fishy so I bailed. Probabbly a scam.

Just reveived that same kind of call, this time it was a man.  I believe they called me before.  I did not want to hear what he had to say after saying "I won a 25 dollar gift card from Walmart."  This is harasment.  It makes you not want to order on line for future purchases.  Especially when they call your job to harass you.
