Not had one of these for a while - your uplifting best-customer-service-ever stories - let's hear them! I'll kick off with one hard to beat:

I recently painted the M-i-L's garage door with Hammerite Garage Door Paint (obviously...) in white, which actually dried a lovely shade of primrose.

I usually do more bad-tempered grousing than actual complaining in these circumstances, but this time, I dropped a (polite) note to the customer care address (Hammerite is an arm of the giant paint octopus that is AkzoNobel).

An immediate response came back with an apology, advice on remedies, and, not a replacement, but vouchers for the truly excellent Sikkens products - 2x Rubbol primer and 1x the matching Satura top coat - enough to paint a football stadium (if it is quite a small stadium, like Loftus Road), and retailing at a nose under £120?!

A brilliant snowy-white door, and I am no longer having to cook my own tea. Thank you Ryan from AkzoNobel.
