I ordered a poster for my 13 year olds birthday 18 days ago. I am frustrated that not only hasn't it arrived in the promised 12 days but it hasn't arrived at all!, I can't track it, no-one has replied to the 3 emails I have sent, the phone number is American... Where is my poster? I think this is my worst online buying experience and would not use zazzle again. Wish I had read these reviews before I ordered.
