Who called from 4322184888

Cell phone calls. Leaves no message.  Call around 8pm each night.

No message, calls 2 to 3 times in a row.  Who is this?

I answered this today they say they are responding to a online survey that I did (I don't do online survey's) and that they are suppose to give me 160.00 gifts from wal-mart. She asked me to open my online brower on my phone and she would give me the number to put in. I don't have a online browser on my phone. This sure sounds like a scam to me.

Keeps calling, no one ever on the other end when I answer. Calls at least 3 times a day.
