On a similar topic....
A few weeks ago i packaged all my unwanted vibes up, filled in the rabbit amnesty pledge and sent the package off to Lh, expecting Oh points to be credited for them. A couple of days later i had an e-mail saying that a refund had been put back in my bank account. Instead of just giving me Oh points for giving the vibes up for amnesty, Lh had refunded me for the toys (not that i'm complaining, Lh always go above and beyond!)
On my rabbit amnesty page it still says 'we are still waiting for your previous items to be returned', and like you say, there's no way of changing it.
I suppose contacting customer service is the answer :o)
