Injector cleaning

Looking for injector cleaning business suggestions.
I have 4 2.0 injectors that I would like to send out for testing.

Back story:
I was battling a surging issue and sent four of my spare injectors out for cleaning and testing. I checked each with a 9V battery before sending and they all clicked.

I first looked at Witchhunters, which I had used before, but they went out of business. On their website they recommended Advanced Injector in KS. So I packed them carefully in bubble wrap and shipped them off. When I got them back they were loose in a flat rate box with some papers towels shoved into the box. Not individually wrapped just rattling around in the box.

I installed them and the car would not run at all. Since I was having other issues I checked everything else before pulling those injectors and tested them with a can under them. 3 did not flow at all. And after removing them I found they would no longer click.

So I put my old injectors back in, and the engine ran.
I don’t know if they will work now since they don’t click. I thought about tapping them with a plastic hammer. And trying the 9V battery thing again.

But in the meantime, I would like a couple suggestions on places other than Advanced Injectors in Kansas, whom I do not recommend.
