I searched for a number for the camera company Olympus in this site's database to contact their camera division customer services and was amazed to find no 084/7 alternative listing.  I foolishly assumed that a company like Olympus would be bound to use 0870 so didn't even visit their own website.

Now I visit their website and find the number quoted is 00 800-67108300.  A Freephone number that is free of charge from practically any landline in the western world.

Hats off to Olympus for exceptional customer consideration.  But if they can do it why can't everybody else?
