I have the very same problem and was told that they can Tap the threads on the drain pan plug, some auto repair shops over tighten the drain plug and it strips the threads, usually no universal drain plug works if there is no threads left or not much at all, so it's best to have the shop that damaged the drain plug by tapping the threads or installing a new oil pan. I was told by my mechanic that they possibly could just tap the oil pan and it would be okay as long as it is not too badly damaged.
