not trying to take a side here but....
This is exactly why I carry my own gear to and from the boat every time.
Most crews as good as they are have a rough time moving those HUGE bloody suitcases that divers pack, and when you have to lug them across a boat or two to get them on to your boat, by the time they get them there they drop them on a hard deck.
I have had one pinch hole in a bladder, and I KNOW I didn't cause it.
So I had to figure out how it happened, it turned out the ONLY thing that could have happened was the crew moving my kit.
So now (I work as an Instructor) everyone knows not to touch my kit, I move it and lug it to the boat myself, No one touches it.
It's a bit of a joke really, but why should I trust my stuff to some bonehead boat-boy who doesn't give a damn about how much my equipment costs to repair or even replace?
I bet if you could find out where the problem came from, you wouldn't be blaming the company that did the original repairs.
On the other hand, I have built my repair shop on the quality of other peoples service here, and I have done fairly well out of doing HIGH quality repairs in an area where doing the least is the norm.
Just my 2 cents worth...
Cheers
