<human>: I ordered Leeds Festival tickets a couple of months back but accidentally selected the neighbours house number rather than my own (Drop down house selectors are the worst) and the tickets were delivered and confirmed delivered by DX Delivery to that house. However, after going around to their house asking for the tickets, the neighbours denied it completely. 

The tickets were £230 in total so it's not like it's not a big deal. We've had problems with the neighbour in the past that have lead to police involvement and it was fairly obvious that the 50 year old guy and his 70 year old dad weren't being fully truthful. 

The first time I went around I simply asked if anything had been delivered by mistake and he said nothing had been delivered and checked with his parents if they knew anything. Apparently they did not. After going back home and rechecking the emails and delivery confirmation, I went back to ask again to face the father this time. From first seeing me he was close to shouting, I asked and told him I had confirmation that they were delivered there but that got me nowhere.

This is taken from the delivery alert email (not the confirmation).

>**Will I need to sign for the tickets?**

>In most cases yes, but our secure delivery agent is given the option to post these tickets rather than gain a signature on this attempt to this address only.

The tickets were not signed for but were confirmed to have been posted on 6th Aug 2015 at 08:09.

I really don't know what to do here.

Can you give me a shortened version of the text?
<bot>: the neighbours are denying that anything has been delivered, we've had issues leading to police involvement in the past and I'm sure the neighbours are lying.
