Ok so I got all my stuff today thanks to scan, however I had a set of Z-5500 turn up DOA I suspect from the way they were handled in transit, I've rang up and got a RMA sorted for replacement but I was wondering if I have to stick the RMA number on the box somewhere or does the delivery man who's picking it up tomorrow have all the paper work for it ???. Oh and what time line am I looking at for a replacement set to turn up at my door as the woman on the phone said two weeks . Many thanks.
