I don't want to be overly harsh and since I haven't resumed building after my move I don't have a dog in this fight but I can ony say that perhaps you should have bought a frame from one of the builders in your area and there are some great ones. You didn't pay a lot for your Mercian and nothing you've noted seems out of the ordinary for Mercian. Many of their frames come through with the sorts of things you note although to be fair only the decal being off center is really a "flaw." They just aren't as picky as Americans.
