I have a same phone call, from Best Buy    ,phone#is 1-713-305-2954 is to  call

Text to my cell.
"Your entry in our drawing WON you a FREE $1000 BestBuy GiftCard. Enter "972" at www.bestbuy.com.bxwt.biz to claim it and we can ship to you immediately!"

Pulled the address up and it looks like BestBuy and sates there are 91 of 1000 remaining.  Not going any further with the scam.  Beware.  Marketing ploy to obtain good telephone numbers and email address.

Text STOP!  in return to them and legally they should stop any further texts to your phone.  Nothing is safe any longer.  This number is now in my Black List app on my iPhone.  Never again!!!!

Just got a text saying I won a BestBuy gift certificate.
