In which case I am sorry to say that unless there is defect that you could show to a judge you have no claim in negligence which will succeed in court.
Even if there was a defect, the value of the claim wouldn’t make it worthwhile going to court and you could be castigated by a judge for wasting courts time over what seems to be a minor incident. Indeed he could even award costs against you even if you won.
To be frank, I would simply return them to the shop and ask for my money back, or if the maker (who has no legal liability as that rests with the shop) will deal, send them back to the maker.
I appreciate that this isn’t the answer that you wanted but there is no point in me misleading you.
Does that answer the question?
Can I help further?
