The post is titled "What to do if you can't contact a supplyer". You do not appear, in fact, to have tried to contact your supplier so what's the post about?
From a suppliers point of view:
(1) please remember that we are in the run up to Christmas. Fleetscale, and no doubt others, are inundated with orders from all over the world requiring goods for xmas.
(2) remember that most suppliers for this hobby are not overstaffed. If you sent an order by snail mail there is not the infrastructure to send an acknowledgemnt by post i.e. no secretaries polishing their nails and sending acknowledgments. Usually it's just one man and his dog.
(3) the law allows 30 days for mail order goods to be delivered
If you are concerned because you have not received the goods in just 7 days then you should ring or e-mail them.
Ordering for the model boat business is not like ordering from Amazon with their huge wharehouse of stock and hundreds of staff and delivery the day after you sent your order.
