The carpet inspector, when I asked him, advised me that my argument was with the shop and when I phoned the consumer advice centre they said the same.
I have looked on web and read about pile reversal, it says that it is not classed as a fault but a phenonimum that happens perhaps in 1 in a 100 carpets and does not deter from the life of the carpet, however it looks horrible and makes me ashamed of how my home looks. I wondered if I had any chance in taking the carpet shop to the small claims court, that is why I have joined this forum to see if any one has had any joy with a claim. We paid with a debit card.
