Missing Apple Watch from the intact box
I bought an Apple Watch from Central World Apple Store Bangkok Thailand for my brother. After unboxing the intact box we found everything was there except for the Watch itself. After several times of trying the store they asked me for the documents of proof. Please note they didn’t give me hard or soft copy of the invoice. Anyways after a week they confirmed my purchase and took 7 days to investigate the issue and revert. After 7 days they replied they are still investigating and would let me know as soon as they find the result.
what should I do now?
