Pues señores, segundo email que les envío, segunda respuesta genérica que me dan, esta vez diferente a la de las 48 horas:

[...]However in this case, I can confirm that this a pre-ordered item, but its price has only reduced after it has been released.

Unfortunately, we cannot extend a refund to you for the difference between the original price and the lower price you saw posted on our website. We can offer a lower price for new purchases, but we cannot extend these discounts to completed orders.[...]

Me han debido de ver cara de tonto. Les he enviado un tercer email poniéndoles a parir (de buenas maneras). ¿Por qué a mí no quieren devolverme las cochinas 5,12 GBP?
