Hopefully, you just got caught up with the Chinese New Year Holiday. I believe things have slowed in China since January because of preparation for this Holiday. It is concluding this week, btw.
I also got a custom order on-hold (with another vendor) because of this too. Although, unlike you, no payment had been made yet. I believe someone in this forum also had to postpone his order to March for the same reason. So hopefully, you'll get some news next week.
Btw, I have no experience with Workswell.
