Are "they" willing to correct the problem?
Yes, I have a solution that will solve the problem.
It is not a very popular one, though.
it involves removing a tile and a half on each side of the crack.That could mean a path four tiles wide, depending on the location of the crack.
Remove all the thinset to the float.
vaccum like a madman
Skim coat the float and screed voids with acrylic modified thinset.
You will need to use a crack isolation/supression membrane over the voids and beyond one and one half tile distance in both directions.
I like to apply the membrane over floated exterior decks as a preventitive measure.
Your installer should "handle" this.
