They wanted me to type this into my computer Best Buy.com

Got a text message from this number (I pay for those, they aren't cheap) telling me I won a $1000 Best Buy gift card and to type some stuff into some website.  I don't know if this is related, but I have also been receiving three calls a day (at minimum, weekends included) from a number that is blocked, they left a message only once.  It was mostly mumbled, barely adequate English with a heavy accent.  AT&T says they can't block calls from 'private' numbers, so they're no help.
