I do understand that issue and I sympathize. But to my mind, based on what you have told us so far, it is the more expensive courier or nothing. I don't believe this is amenable to a technical solution.The problem arises while your products are in the hands of the courier and they do not seem to be prepared to solve the problem. From what you have told us the courier firm is well aware of your concerns. More detailed evidence won't make them more aware.
I know this is not what you want to hear.

PS.. Don't worry. I am not going to say this again
One man at HQ is being troublesome. Our local depot (a major city - therefore with a lot of influence) is on our side. They don't want to lose our business, it's a good-sized account. We don't want to have to change courier.
This isn't happening to all parcels - obviously - and we are simply trying to find out if we can track where the breakages are happening. Often with couriers it's certain depots that cause problems, or certain handlers or drivers. If we can pinpoint something that shows where it is happening, or any pattern (for instance it could be a particular worker at the local depot or one of the national hubs) the courier company would want to know that and would act.
The idea of the most expensive courier - that is not financially viable - or nothing is simple not a practical option but thanks for your input.
