I think that most of our TD's would be the same. These are counterfeit items bought off the internet from someone you don't know 1000's of miles away. The TD's are out to make money, they are not your friend. As long as you managed to get the problems resolved then it's more or less acceptable. If not then contact a moderator here.
Sorry OP, but with my limited knowledge it sounds like the crown spring. I have a similar issue with a UN Maxi Diver. I can just about get around it by pulling the stem out to time setting and pushing it quickly and firmly home. I've been told that it should wear in a bit and get easier.
