I have been asked by a friend, they have seen a massive rise in the number of complaints of items not being delivered.
However they send everything tracked and have proof of delivery, typically a signature from the recipient, or photo of it bein left in the designated safe place.
Customers get aggressive and deny the evidence, so there is a strong suspicion it is fraudulent.
What can done?
it happens and isn't common in relation to the total successful deliveries.
Happens once in a blue moon.
The truth is even if it's tracked with a signature and everything if the customer strongly believes it to not be delivered then you still have to take the hit for it.
A lot of companies use temps and inexperienced delivery people to cover christmas peak period and they do get the deliveries wrong. They misread the address on they deliver to the wrong door which is numbered the same to another property adjacent to it.
If the customer is adamant they didn't receive it, the tracking etc. really wont stand up in court. Often the photo is of the package without much surrounding detail to prove it was delivered to your address. Or the signature is a squiggle that doesn't prove anything.
If you are sending high value items - then only send it via special delivery which is much higher level of service. Where the drivers are experienced and only allowed to deliver to the intended recepient and get a proper signature.
I delivered as an amazon driver and you really have to be careful and double check where you're delivering. I had one instance where there were 3 doors and they were numbered 1, 2, 1.
The first #1 originally had their front entrance on the adjacent side street. They decided to change the layout of their house and move the front door to the other street. So now they have they have 2 front doors with the same number.
There are a lot of development works going on all the time. Now properties being erected in gaps between buildings. So they have #56, then they have #56a #56b (these two new proprerties buit in the gap between #57 & #57) . #56 is then converted into flats so they have flats 1,2,3,4 in #56. So a temp worker has a package for #56b and arrives at #56 and assumes flat 2 at #56 is #56b.
I had customer complain they didn't receive a parcel sent on 4th december. They were 6 miles from me. So I decided to re-deliver again so they get it in time for Christmas. Then they get back to me saying they received their item after boxing day. Which is annoying as I wasted time and money on an item. It was misdelivered and the person who received the item took their sweet arse time to post it into their neighbours letterbox.
So don't assume customer is lying to you, often they genuinely haven't received it and it was misposted to a neighbour by an inexperience courier driver.
