From what I have seen of these new mouldings, your moulding company needs to run a small batch to validate thier parameters, things like mould temperature, injection pressures, cycle times etc.
These coupled with venting added in the correct positions (tiny modifications 1- 2 days max) will sort out your sinkages, short fills etc.
The greasy finish you mention is most probably due to excessive release agent used when running the mould for the first time (reduces the risk of the moulding sticking in the tool).
I have been designing plastic components for over 10 years now, and alot of your issues with Chinese moulding companies are well known, regardless which company you chose over there, they just work diferently to us.
I am very optimistic though, when these parts are run to the correct production processes, perhaps with extra venting, your cosmetic issues will be resolved.
