Print off the forms I gave the link for...
Take the retailer to small claims on Sale of Goods Act - unfit for use rules
Take the manufacturer to small claims on Consumer Act 2015 (which DOES handle foreign manufacturers - I took Goodyear HQ in the US to small claims after their UK high street tyre firm, HiQ, wrecked a vehicle of mine and I won cos they did not take me seriously) for warranty refusals
Do not play their game of he said/she said cos thats what they want you to do
@AquaBarb
Take them both, two sets of forms (one for the retailer, one for the manufacturer)...when they get the court papers on their doormat, they will be begging to sort it out amicably with you
These firms depend on customers not having backbone to take it further than a disgusted letter....its what they do and its why I never take any notice of warranties.
You have tried to deal with it in the nice way, now get those gloves off and use the small claims court system...more people should use use SCC cos you would not get so many people being shafted by firms
I am more than happy to help you word the forms if wanted....I have been told that I have a way with words when I get pee'd off with companies
