Amazon.fr order issues

[McCrutchy]

OK, so I had just placed my first ever order with Amazon.fr for three already released BDs that were in stock. I used standard delivery, which I assumed did not include package tracking, and I received a dispatch notice informing me that they were estimated to arrive on 26 March.

This morning I wake up to find an e-mail sitting in my inbox informing me that the items were undelivered and have been returned to Amazon.fr, and it seems I will be refunded.

Now, I realize that, for whatever reason, EU Amazon sites often ship batch orders to the USA much quicker than a single item order, but I'm still upset that they obviously used a service that required me to be present to sign, and also delivered the item at least 4 days early (if that is exactly what happened); essentially, I'm still confused as to what happened with this order, and whether it even made it to a delivery truck in the USA or not.

Is it feasible to contact Amazon.fr customer support? Do they have representative who can liaise with English-speaking customers, or not?

And should I expect, whether standard or express delivered, that I will have to be present for a package delivery from Amazon.fr? How would that be possible without tracking information?
