FALSE ADVERTISING & MISSING ITEMS IN ORDER.

I originally purchased a Summer Print Pyjamas, when I ordered it said it was a 2 piece in the description. My original invoice say its for Pyjamas. Now my invoice on the app has changed to Summer Print Pyjama Shorts. They haven't sent me the matching shirt and they trying to pass it off as I made the mistake. BUT the items description changed once they noticed they advertised it wrong. WOW WOOLWORTHS I WENT FROM LOVING YOUR SERVICE TO HAVING DOUBTS ABOUT EVER ORDERING AGAIN!
