I preorder the Galaxy s21ultra in exclusive phantom brown colour. Seems that if i changed my mind and i would like to cancel the preorder, it won't be possible .
@Catt78: That doesn't sound right, therefore I recommend reaching out to out Shop Team via the link below for further clarification. It may be the case that the additional production time required for the exclusive colours may be preventing you from cancelling the pre-order, with the release date just around the corner, however the Shop Team will be able to look into this further for you.
I set up a return for my week old Galaxy Note 20 Ultra last Sunday (17th) so that I could preorder S21 Ultra. DPD collected it from me on Wednesday and just got an email from Samsung an hour ago to say that refund had been processed. So it's a pretty quick process.
