I came on here to say just the same. I felt embarrassed for the guest and QVC should issue some sort of apology. I don't want to know what AD thinks, I want to know about the product and how to use it. Why have an expert guest on at all if they're not going to be allowed to speak?! It completely ruined the show and why does she have to shout? She knew she was doing it too as she kept saying that she'd let the guest have a word. Someone should have just switched her mic off. Don't the gallery have any control over the shows?
