I'm sorry this happened to you, but you got burned on this one. The TD will not ship out replacements due to the fact the package was delivered and accepted, so it's unfortunately a loss. I would also be curious about the co-worker situation, but without evidence you shouldn't accuse them of anything.
Many members, myself included, request multi watch shipments separately to avoid total loss situations like this. It also reduces the risk of customs seizing a package of multiple watches and considering you a dealer, which will land you in serious trouble if they pursue it.
RepGuy sincerly co-workers really are not at all the kind. they are shareholders and trusted people I've been working for the last 5 yrs and would not need to steal 350€ each.. (btw... 2 out of 4 were waiting with me for the watch).
