Hello, my name is ***** ***** it is my pleasure to assist you with your question today. The issue with pursuing them for further compensation is that in law you can only really ask them to cover you for losses which you have suffered as a result of this delay. For example if you had to get other furniture to replace the one that was missing, as a short-term fix, then you may have been able to claim for these costs, but if all you suffered was a delay and inconvenience and you did not actually suffer real losses, then the law will not compensate you any further.So the offer you have received so far is probably more than you what you would get if you took this further, such as to court.
It does not stop you from trying to uh them further and hoping that they exercise their customer satisfaction skills to try and offer you more but if they refuse, then be realistic abort what you can actually get if you were to legally challenge this, and it is unlikely to be more than what you have already been offered
Happy to answer any related queries if you have any?
