Perhaps we could turn this into a good service thread.
I had a 30 month old Hotpoint fridge freezer fail. Out of warrenty. to cut a long story short it wasn't repairable and 'otpoint said on'yer bike.
I made a claim under the CRA with AO. They grasped the issue, said they'd phone me back once they'd spoken to 'otpoint, they did and gave me a prorate refund for 29/60ths and took it away (after I argued they owned the majority - 31/60ths of it and offered to store it for them at £10 a week).
Another one is Winfield's.
We bought a Coleman Airbeam tent from them 18months ago.
The first time we used it I noticed water at the base of one of the beams and asked them about it, they contacted Coleman and said it was condensation - I wasn't happy because only one was affected but let it develop. This summer our trip was rainy, the problem recurred, I found a leak in the taping of the seams,. I raised it again with Winfield's who grasped the issue, spoke with Coleman and got them to agree to replace the whole tent. Even transferring the replacement to my local store (not the one I bought it from).
