VS Amex

Sorry for asking such a thicko question but how do you go about cancelling a VS Amex card? I have checked their website but cannot find any info on how to cancel.
Is it a straight cut up the card and post back to them with a covering letter?
I feel I no longer get any useful benefit from the card anymore as my travel with VS is now non existant since most of my travel is with BA or *A and their reward options are rubbish. If I want VS I will just pay up front.
Thanks in advance
