Evri complaint: Missing goods

On Saturday 5th October’24 a female courier from Evri came to my house at approximately 17:30 (originally scheduled for 13:30-15:30). She handed over two small packages (one for me one for my daughter). She also asked me to take a parcel for number 8 (neighbour further up the street).
After she had left I received email notifications from Evri to say that my packages had been delivered inclusive of the JDS package which I was expecting but did not receive.
I immediately contacted Evri JDS.
JDS have informed that Evri has ed delivery of my order. They will not supply me with this evidence as they state it is confidential information.
On your ‘rate your driver’ section of your delivery email it does not show a profile of the driver ie photo name.
I would hope Evri have details of who the courier was.
I have taken a photograph of the larger package which she asked me to take in for number 8. I am hoping that this wasn’t used as a decoy to suggest she had delivered the JDS package???
I have also obtained cctv footage of her delivering the aforementioned packages noticed that she doesn’t attempt to knock at number 8 raising further suspicion that she has used their package as a decoy.
The package contained £175 worth of goods.
Why I am still waiting for an Evri representative to make contact is beyond me!?!?
