I hate big manufacturers when they do that. Quickstep tried to do it to me last year but I just kept threatening the supplier with legal action. The law is so focused on the consumer that the supplier eventually buckled and paid my whole claim just by threatening action. It included cost for removal, disposal, replacement, new skirting and redecorating.
Have you tried going through supplier rather than manufacturer? Not fit for purpose? What about legal cover on house insurance.
