As side issue, this not make sense.
It say that client get deposit applied to final week of care. So client give you 2 week notice, then they not have to pay until last week of care. They just have to pay for one of the 2 weeks notice because the sentence before this says their deposit is applied to the last week.
Then your paragraph further contradict because it say that the depsoit will not be refunded but the first sentence said it's given towards final bill.
If you copied this from contract, you urgently need amend contract to remove all contradiction.
