I've been wrestling with a mouse/track pad problem on my Vaio laptop (Win7, model nr. VPCSA4T9E, bought in Nov. 2012, in Denmark)  and have been trying to get some help from the Sony website, preferably an email address for customer service.

When I'm asked to enter my serial number it keeps telling me it's wrong. I've checked both my Vaio Care on the laptop in question and turned it upside down and checked the sticker - same number in both places and still it says it's wrong!

What's going on here?
