YODEL claim they didn’t even get my parcel for delivery

So I ordered a present for my other half for her upcoming birthday. It was coming from the states and was a unique album. Under the care of UPS, it happily bounced around the states from depot to depot being well looked after and well tracked for about 10 days.
Then it hit UK soil. 13ten Citipost received it and claim they passed it on to Yodel. Yodel claim to have only received the paperwork.. So both now blame each other for the loss and as this was a one of a kind item, I can only hope for a refund.
Both can’t explain what happened and blame the other. Terrible!
