Looks as though Amazon have dispatched the GPU to me not using their own services and have used royal mail tracked and signed for. I might be shit out of luck. Guessing they're doing that based on the price. Not 100% on if wrong Item received would work considering this?

You obviously want to "receive" It to claim that the Incorrect Item has been sent, so whether the consignment Is tracked and signed on delivery, has no negative Impact on the wrong Item received method.

In fact, It works to your advantage.
