You have to call them and ask for an apology......
You know this is the 21st century......
{not to take their side.......when the gun gets to them, in shipping/receiving,
they log it and give it to repair, who, when finished with the repair,
repair gives it to shipping, who sends it to you.....
customer service is only involved if you call them....}
The repair person is not gonna write you a note....which is sad.
As long as they fixed it.........
