Hi guys my month old TomTom Go has gone faulty

It give me the remove card red cross on the screen. It was working fine until I connected it to my pc to do an update, now the bloody things doesn't work.

I can't find a contact number for the TomTom customer services anywhere, can anybody help me with that, or do I need to send an e-mail to them?

Anybody help me please ???

Cheers
