Has any professional drying work been carried out??
As said above you can't just waltz in and do a standard carpet clean after a flood. Unfortunately many people think this way, they just think that if their carpet has been affected by anything then "cleaning" is the answer.
If it hasn't had dehumidifiers and airmovers in there, and had moisture readings taken, then there really is a need to get it properly sorted otherwise it could turn in to a very expensive problem a few weeks or months down the line.
By next week, the carpet may have lifted in places where the adhesive has failed or the surface of concrete screed has disintegrated.
What about the walls? Water might have worked its way up the walls, which isn't always visible. This could lead to later problems, including the skirtings rotting away from behind.
Sometimes people don't even realise this is an insurance issue. I'd ask them if they've contacted their insurance company, you'll maybe lose a little job now but certainly curry favour for next time they are looking for "just" a carpet clean.
Sorry to be so blunt
