have you re indexed your new domain with bing?
if i visit your site at:
www.bellezamedispa.co.za/
and search for "spa" i get one result.
if i visit bing.com and search for:
site:www.bellezamedispa.co.za spa
i get the same 1 result.
it doesn't seam like the www.bellezamedispa.co.za/ domain is properly indexed at bing.com.
