I was part of a two man delivery crew for a major UK retailer dealing in Electronics, Furniture etc. We took the usual precautions for this kind of job such as a customer signature, date and time all signed for by the customer. Only leaving an item with the neighbour with prior written consent and if the customer was not at home they would also need to provide written consent before the delivery and we would photograph the item outside of their door.
Since I wasn't self employed like DPD, FedEX, UPS we didn't deal too much with DNA like one of those drivers would. We would occasionally be asked questions such as "So and so didn't receive their item, are you sure it was the right address" at which point we provide everything we have. As a driver, it's obvious when a customer is trying it on. The trampoline you asked us to put beside your shed? No issue there. The new iPhone which you asked to be left outside your door? We see it a mile away and so do the administration and support staff.
The problem on our end however is that you cannot "prove" that the customer received the item, as discussed here if somebody has signed for it, be a neighbour or someone at your address your chances are effectively 0. But if it's left outside and admin receive a complaint a day later there is always that reasonable doubt, even if we all agree that something isn't right. The admin team have to exhaust every option before they consider either a replacement which is priority one or a refund which was a last resort.
We never had an issue with blacklisted addresses as the highest number of DNA from a single address was 2, we were then required to get a signature from somebody inside of the registered address in order to make any more deliveries to that address but no more were placed. It's a bit different like I said for the UPS men of the world as they are generally self employed and are paid per package where as I was under the protection of a company.
