I called Casio today and told them about the new WVA-M640 watch I just received where the "B" button is not working. I was under the impression a defective watch would warrant them to pay for shipping both ways considering I am stuck with a broken watch. Also they are requiring a notorized letter saying I received the watch but don't have a receipt? I don't get what the notary is for and what that even proves? It would be like me going to a notary saying I saved $500 on my car insurance and getting that notarized. The watch was manufactured August 17, 2013 so it's not even 1 year old from when it was made never mind from when it was purchased. I would think right there, that should be enough for them to repair or replace this thing no question asked. What am I missing here? Since this was an eBay purchase I am wondering if that also has any negative effects on them honoring their own warranty.
