#1 - When you strike a bargain on the phone, always ask them to confirm it with an email, so its black on white.
#2 - Even if you opt for the police report, the police will stamp it "case closed" no suspect, no leads, no crime, not worth the time. and slide that bitch into the dont give a f pile.
#3 - Keep comming at them, demand a fucking refund, you just paid 700 bucks for a half the order, without a smartwatch, would you accept the pizza delivery guy handing you a half eaten pizza, or just the crusts, hell no.

This is just a test of patience and if you are in doubt, as also mentioned in another post, find the law texts about consumer rights / buyer protection, if you are within EU you got some really decent paragraphs to throw at them in your email, also if they are on trust pilot or google - write some nasty reviews, if needed make more accounts and claim that "its a friend".
