Don't worry, the maximum waiting time is 15 working days (so over 2 weeks).
Postal service is the problem here, Play-asia usually ship next working business day, the 3 times I bought from play-asia so far:
1) took 10 days to arrive
2) Took 15 days to arrive
3) Took 14 days to arrive
All working days by the way, so wait 15 working days, if you still haven't received it, I'd send them another email.
