Letter to Hasbro: Repeated QC issues

I'm getting more and more frustrated with quality issues lately. I just sent the following message to Hasbro.
I want to complain about the frequent quality issues I have had with Transformers toys in the past couple of years. Many of the toys I have bought have had significant issues. I have been a Transformers collector for a long time, and I treat my toys with care. I'm starting to wonder if I should continue buying Transformers because I can't trust their quality.
A summary of the issues I have had:
Prime First Edition Arcee: One of the arms would not stay on. Returned, but could not exchange due to lack of inventory.
“Rage over Cybertron” Optimus Prime: After transforming a few times, the front hood piece broke off.
Masterpiece Thudercracker: The toy is fine, but the box and instructions did not reflect significant changes between Thundercracker and Skywarp. Plus, the illustration on the box was for a different Thundercracker toy. It all seemed very careless.
Masterpiece Optimus Prime: Parts of the chrome bumper were not painted properly.
Generations Blitzwing: A side piece of the head, and the pin that enabled the three-face piece to turn, were missing. Returned, but could not exchange due to lack of inventory.
Generations Sandstorm: The front landing gear was in the wrong position, such that I had to pop the head off in order to transform it the first time.
Beast Hunters Voyager Optimus Prime: The sword got stuck in the right hand, and I was unable to remove it without breaking off the handle.
Masterpiece Soundwave: On Buzzsaw and Laserbeak, the top fins on the weapons have such tight hinges, and the plastic is so soft and thin, that it’s very difficult to transform them without bending or breaking the fins. I have already broken one, and I have been very careful.
