Yes, contact FC and ask because it may be a default setting for your Country ... not saying this for sure, but if you selected one carrier, and your order defaulted to another, there has to be some type of system setting defaulting to Singapore, which may, or may not be for good reason.
Have you used HKP before from FT??
I did use
Singapore (free) FC/FT 4-8 weeks
Honk Kong (free) FC/FT 2-5 weeks
Swiss (free) FT 6 weeks
Sweden (free) FT 7 weeks
Malaysia (free) FT for batteries 2-3 weeks
China e-packet (+$2) FT 7-12 days
I really find the best e-packet China, i don't care for extra pay, i usually place big orders and have no problems.
