Who called from 3479774623

Got a text from this number claiming I won a free $50 Walmart Gift voucher. It said to call 1-877-552-3586 to redeem.

I just received a text message stating that I have been selected to receive a FREE $50 Home Depot Gift Voucher and to call 1-877-552-3585 to redeem. It also says TXT STOP TO STOP.  I did not text to stop because I figured that may confirm this as a working number and I may get more.
