Does it make sense to take further steps against the offer of 'final settlement' from the kitchen competitor?

Questioner

A few months ago I bought a kitchen with a granite top. I installed it myself and mounted the top. When removing the packaging material after the top was placed, there appeared to be a lot of scratches on the edge from grinding. Contacted the kitchen competitor where the kitchen came from, no big deal, they could fix this on the job. They sent someone for this, but he could not fix the damage. The solution would now be to dismantle the top and return it to the stonemason. The kitchen competitor could dismantle it, but all damage that occurred is at my own risk and expense. In addition, I would have to install it again myself. Because we were now a few months further and the contractor continued (which was possible because the problem would be fixed on the job), the chance of damage is 100%. This is because the plasterwork is made into the top, the top is slightly stuck between various walls and cabinets and all equipment is mounted in the top. I would then have to have the complete finishing done again. I don't see this coming, considering the extra costs that will be added to my budget. The kitchen competitor understands this and wants to offer me 300 euros 'in final settlement' after long discussions, but I don't think this is realistic considering the costs that would have to be made. Or what the top is still worth. The kitchen cost a total of 6,500 euros. So my question is concrete, does it make sense to take further steps here or will this cost me more than it will yield?

Because the sheet was delivered with a defect, you now have consequential damage. That damage should in principle be fully compensated, whether it is worth the effort of a follow-up step depends on the total amount of the damage.
