Hey guys, so I recently bought the pen that I have described in the title from Ebay, it was the ballpoint version. I'm trying to get a refund on it because I believe to have been duped or ripped off. Now I was to believe that the serial number on the clip is supposed to match the one supplied in the certification booklet and the handbook. They do not, however the seller assures me this pen came straight from a registered retailer and has not been tampered with. The clip number in the paperwork is PW2344002. The number on the actual pen clip is XW1058636. Surely this means that the clip has either been changed or the paperwork is to a different pen. Am I wrong to think this? Is there something special with the diamond ones or am I right? Thankyou Ben
