We are here to help each other but how can we help when what we see is what you see just base on the QC photos? Anyone might have a possibility to be wrong sometimes and when it does, there is nothing much we can do about it other than suggesting you to go back and look for your TD. So in the end, everything goes back to the same again which is only between you and your TD for any issue or doubts.
You can always request for a clearer photo of the particular area where you think might have an issue with when your TD tell you it is ok but you still have your doubts. Anyway, I don't think TD will wanna risk their reputation and becoming a not honest and lazy dealer especially when you are a member of a rep watch forum as they know that when things like this happen, it will spread very fast and cause damage to their reputation.
And also they will still have to spend more of their time to solve this issue on a same deal which in the end, time lost, reputation lost, customer lost.
Not really worth imo.
