Evri complaint: Lost returned goods

Dear Sir / Madam,

I am writing to you to raise an issue about: Online shopping

The issue that I have experienced was: I sent my return goods to Boohoo via Evri on 6th April. I packaged the parcel securely, and I have the proof of postage from Evri. Boohoo have received my package, however, there was only one item in the bag when there should have been 8 items. I have only been refunded for one item totalling £13.60 as they state that the other 7 items are missing.
Boohoo have checked their CCTV and they have said that only one item was in the bag.
I have been in communication with both Boohoo and Evri, but neither of them will take responsibility for the missing items which total £96.40.

It occurred on: 06/04/2024

This meant that I am £96.40 out of pocket (I owe this on my Klarna account). I am incredibly frustrated and upset because I have followed their return instructions exactly and have done nothing wrong, but neither company will accept responsibility for the missing items which I can only presume have been stolen.

I would like a refund of £96.40 to my Klarna account and an apology for the stress this is causing me. This is money I do not have.
