Hi guys. I desperately need an advice on what to do next.

My partner purchased a rather very expensive ticket for Eminem show as my Xmas present. (worth $306, but she paid $450 for that as show is sold out).

It's alright that letter/small parcel was not delivered before Xmas. 

On boxing day we went to Coromandel for a night. On the morning of 27th, she checked TrackNTrace. Parcel showen as delivered on 7.35am on 27th. Cool! Got back to Auckland evening 27th just to find out that nothing is inside letter box :(

Morning 28th called courierpost to check where is my ticket! They logged enquiry and told me that they will contact me on Monday 30th. 

On 29th we went to Bay of Islands for a night. Around 4pm on Monday received txt from courierPost that they confirming that parsell is left under the door (note: we're living in apt building on 9th floor and never had courier driver gone all the way and get to the door. Always intercom only. if we're away - drivers leave card to collect). Got back to Auckland around 8pm. Checked everything at home - no letter.

Called courierPost today to let them know that we still missing a letter... they closed enquiry as driver confirmed delivery. I insisted to keep it opened (not sure if that helped, but they assured me they did). 

We also have cameras in main lobby... courierPost asked if i could check recordings, which I already requested from building manager, but its public holidays and I doubt I could get it for the next 2-3 day :(

Parcel was not signature required :( 

Surely i will check recorded video if I can.

what now? can i somehow prove item is not delivered without video? it's drivers word vs ours... but as i said earlier for the past 8 yrs living here I never saw delivery driver come up to the door before :(
