Technically you can flag a shipper. After recording delivery drivers stomping across my landscaping and literally throwing packages at my door, I got them to stop using that particular gig economy delivery service for my packages. Getting them to do feels like pulling teeth though. It seems you can't do it for a single incident but interestingly they'll gladly give you the number to the local shipping logistics company, so you can call and yell at them.
Was it lasership? I've had packages never delivered by them. I'm assuming the courier is just stealing them since the package will say "out for delivery" multiple times that day and then never show up. They don't respond to emails or calls so anytime a package is set to come through them, I know that I'm probably not going to get it. Nobody has questioned my reports that the packages aren't getting delivered most of the time. I guess the vendor already knows how much they suck but for some reason is ok with the spillage? Maybe the cost savings for using one of these gig economy delivery services is so cheap that its still worth it after having to replace customer orders that get stolen. Maybe it's like doing business with the mob, there's just a certain amount of money you're going to have to lose due to rampant theft but the money you save by getting around the normal business costs makes it worth it.
I got Amazon to avoid shipping things to me using their own execrable AMZL (Amazon Logistics) service, by emailing Jeff Bezos. They said from now on they would only use AMZL if there is no other way to ship (e.g. for same-day shipping). So far this has been a good solution.
