Kitchen Question?

[Guest]

Had a kitchen fitted roughly 4 years ago, some of the doors have started to bubble on the outer veneers (gloss black finish). The kitchen was manufactured by one company but supplied and fitted by a kitchen showroom local to me who have since closed 2 years ago. I've contacted the manufacturer as the guarantee was 10 years and informed them the company I originally went through had closed but they are trying to fob me off, i still have my original invoice and receipt somewhere, what would be my best option to get these replaced? Thanks

It was a manufacturer's guarantee on the doors? What exactly have they said? Do you have the guarantee certificate?
