This SMS said "Please call 877-891-9915"

The (outsourced) operator asked for my "first and last name" which I did not provide.

I asked her to "please identify the company or person" responsible for the SMS and "how they got my number".

She replied "I don't have access to that information".

Then I asked what they wanted and she said "This must be in regard to the WALMART $200 REBATE OFFER" .

I immediately hung up on her and sent a "STOP" reply to the SMS.

Be sure to file a complaint with the FCC.  http://esupport.fcc.gov/complaints.htm

It's very fast and easy to submit a complaint online.  I complete one every time I receive an unwanted text message or phone call.  

If nothing is done, these telemarketers/e-marketers, etc will just keep on doing it.
