Hate to say this, but you are more than likely correct on your assumption, Amazon never seem to take into account evidence of weight, or photographs when they consider these items.

I would recommend appealing the decision as soon as it comes in, then when the appeal gets rejected go straight to the managing director team, this does sometimes help, but not always, and don't think it is quite as effective as it used to be.

Depending on the value of the laptops, I personally would then go after the customer, courts will look at all the information that Amazon refuses to. Amazon does not allow this in their terms, but I have done it on a few occasions and not had any comeback, but it is always a risk, so you should be aware of this.

Of course, I hope I am wrong and that Amazon do not side with the fraudster for a change as there is far too much of that on here.
