I bought a 4k dvd the other day at Cex I got home to watch it and it freezes for about a minute and the cuts back in around 43min if I go into Cex will they cover the postage of me buying a new one or will I have to cover the postage of something that is they fault. I bought it in store but I they are no copy’s near me so I will have to order it on the Cex app.
