AGREED! They've dealt with my own quality control issues with great professionalism!
This occurred back in Dec 2014 with TAS Catwoman...
Selina didn't even make It out of the package before her arm fell off. I had the water boiled and everything to work out her joints.
I attempted to fix the issue with a small screw and a dremel. A good fix while I contacted DC Collectibles for a replacement:
A month later, I received my replacement Catwoman from FedEx, along with a note of acknowledgement:
While the breakage issue shouldn't have been an issue in the first place, I am impressed with how DCC handled my situation... I've continued to support the line!
