No, in short.
You have a claim for the sum that you paid but they are not disputing that.
If you had to pay extra for the same kitchen then you could argue maybe that you would have a claim for the difference although it is not the best point.
Disruption is not a head of compensation in law.
Neither is distress. Also, you are not responsible for her distress. You are having to put up with the same issues as she is and you are managing your distress.
I suppose, in academic law, there would be a claim for things like phone calls although in practical law it is never a sum worthy of a claim.
This is always presuming they are in breach of an undertaking to complete your kitchen to the specification required. It sounds as though they dispute that but are settling in the interests of good business.
If you complain then they might offer a small amount in compensation though.
It is more than they have a duty to do but often complaining works.
Sorry but I can only give you truthful information.
Can I clarify anything for you?
