Useless, very bad contact service.
If nothing happen yes all good, for sure..
Just a little issue and everything go done. 
There is a live chat. With a robot... Then said à human is going to take over. But seriously I truly hope "Antoine" wasn't a human being... This is useless. They just answer every 2min "I'm treating your probleme" "hi, I'm taking care of it" "hi, are you still here" even if I was sending a lot of messages...
Really bad service.
