I had two recent (last couple months) chinese order related blood pressure spikes
One was Aliexpress ( a completely scam seller that fakes fedex shipments) and the second was a direct order from FOSI china web site.
For the Aliexpress fake seller, I reported the scam via ali's online form, and received total refund in a couple days. If I had bothered to read the scam seller's feedback first, I never would have ordered from them.
For the FOSI order, they used a no-name delivery service here in the states, and reported product delivered but I never received anything. Complained to FOSI via email and it took about one month to receive a replacement (local delivery via USPS per my specific request).
I would only order from China now if I really did not care if I lost my money...
