@Harris1234 through all this you managed to keep things mostly civil, refrained from throwing around foul language and dirty insults when things turned a bit against you - something many people do in their frustration.
But you didn't call everybody names. That's a plus in today's world in your age and situation. As irritating as this thread felt at times, you don't seem to be a bad guy.
But bad decisions have been made on both sides.
I do feel sorry that you are in limbo about the whereabouts of the watch. I know the feeling. Had a watch gone missing for almost exactly a year. Then all of a sudden it turned up.
I don't know all the details but I'd like to point out the possibility, that the watch simply went missing en route to you. Given the number of packages that have to be dealt with by postal services daily, things like that just happen. It does not have to be the sender's fault or intention and in my personal case there was simply nothing the sender could do. In the end everyone at the postal services just shrugged their shoulders. But luckily and almost magically my watch showed up after almost a year. I hope for a good outcome for you. If possible take yourself back a bit next time, best of luck.
