1/4 mags were defective - ProMag Sig Sauer P365/365XL 9mm Luger 20 Round Pistol Magazine

I ordered 4 ProMag P365 magazines and once I removed them from their packaging I noticed one of the feed lips was bent upwards and not properly locking into the magazine itself. I tried to load the magazine to test it and the rounds are then pointing at a downward angle after the second round is loaded. This is causing the magazine to not properly feed into the gun. Alongside this issue, I did attempt to fully load ghe magazine during my testing and after the 12th round was inserted the bottom cap had fallen off and will not properly reattach to the magazine.
