On 02/27/2014 I went to the super wal-mart on george claus blvd (store #1875) in severn m's at 11 a.m. & purchased a 65" flatscreen television.  The television was on sale I paid $740.00 for it & thought that was an awesome deal,  ha until I came in from doing the rest of my shopping.  Went home opened up the box & there was no television in the box someone had put 2 cable boxes & weights in the box.  Once we opened it up we immediately took it back to wal-mart they said they couldn't do anything about it I didn't get my money back or a new television & all I wanted was the tv I ended up buying another tv & I still haven't got my money back!
