Are Costa Cruises offering a 30% discount to Concordia survivors?

The internet has been ablaze for the last couple of days over a report that Coast Cruise Lines has offered  cruise passengers onboard the Costa Concordia a 30% discount off their next Costa cruise as compensation for the disaster.
Whilst I don't think Coast have exactly been covering themselves in glory over this incident I'm afraid people that this report is completely false, or nearly so anyway.
