Red by SFR: 3 weeks without telephone nor internet. Impossible to join any human being, the customer service is digital, useless with an internet out of order!...
Their head office doesn't answer to registered mail.
Only by changing the internet provider did I learn my problem was a disconnection of the fiber somewhere outside my house.
Having duly returned the equipment, they still tried to bill me for it.
To be avoided at all costs!
