Fnac.com is quite misleading as it's a French site target to fluent French speakers who live in France. I've been having an adventure with a faulty tablet and their awful support. Because:
1) Nobody there (I mean none of the 20-30 people I've talked to during this time) speaks English or is willing even to try.
2) If you buy online and have a problem, after filiing this (on the phone and in French) they have the possibility to send a request to collect your item with DHL. That's the only positive. But they don't give you any number to monitor the service procedure. You get that only if you go yourself to a store in France!
3) Tried to call them about no. 2 cause I can't go to France and was charged several times for a 10'-20' international call because simply they were forwarding one to the other, until the line was automatically dropping from their side!
4) the online chat doesn't solve anything, they simply refer you about any problem to the phone support!
5) And by the way even to buy from abroad you'll need even to send a copy of your passport. Enjoy :)
