Thanks to the experience I have had with Zavvi I will never be using them again.
I made a mistake during my order by selecting the premium postage option and IMMEDIATELY chose to cancel my order to correct the mistake. Of course, they sent me an automated email that said they couldn't cancel my order, no reason stated, only that they were going to send it anyway and I could return (no indication if this would be at my own expense) it if I didn't want it. What is the point of giving the option to cancel if that option doesn't actually exist?!
I also previous tried to leave my negative review on another site (rhymes with dust, flies a plane) but they deleted it. Very angry and disappointed overall.
