A few months ago I bought a camouflage walkie-talkie for my brand new walkie-talkie. I was just able to give them to him today and we were sad to find that one of them didn't work. We tried 2 sets of new batteries to rule out a battery issue. The children were very upset that they could not play. It's been too long since I ordered them for return and I can't find how to contact the seller.
