In reply to ClimberEd:
I would suggest your best bet is to use this useful info on the site:
Email: sales@wiggle.co.uk
Chief Executive Officer: Humphrey Michael Cobbold
Merchandising Director: Paul James Bolwell
Finance Director: Andreas Panteli
and make up the email addresses of the CEO etc e.g. HCobbold@wiggle.co.uk, H.Cobbold@wiggle.co.uk, Humphrey.Cobbold@wiggle.co.uk, H_Cobbold@wiggle.co.uk, Humphrey_Cobbold@wiggle.co.uk humphreycobbold@wiggle.co.uk etc
You wil receive unknown email address responses from their servers if you get it wrong so that should make it easy enough to find the real email address, and then email them every morning until they've dealt with your problem.
It may be less effort to drive down to see them in Portsmouth though
