NEVER SHOP AT WISH THEY NOT UPFRONT AND THEY DECIEVE

MY FIRST TIME BUYINING THROUGH WISH AND I WAS SO EXCITED BECAUSE I BOUGHT MY KIDS SOME STUFF IN DECEMBER BUT UP TILL NOW HAVE NOT RECIEVED ANYTHING. THEN I GET AN EMAIIL SAYING I NEED TO PAY FOR MY STUFF COMING THROUGH. ALL THIS IS NOT MENTIONED WHEN SHOPPING ONLINE. I WANT MY ORDER CANCELLED AND I WANT A REFUND FOR ALL THE STUFF
