Vinted review: Incorrect parcel delivered

I collected my parcel and found it to be incorrect, I followed Vinted's procedure and reported an issue sending a photo of the parcel.
They contacted me to ask for further pictures of the parcel saying they were going to take it up with the courier. I chased this as my order auto completed on the site and I have been told I have to go back to the seller and that they won't refund me under their policy and procedures. I am going to speak to the seller as she was very unhappy that the parcel wasn't even an item she was selling. The courier had labelled it totally wrong.
