Tom,
You can jump on a Looking Glass router and check if your prefixes have been
advertised by your provider. Your provider may have one. If not, try someone
that has a direct BGP peering with your provider. As common practice, to
keep global routing table small, ISPs may accept but do not advertise
prefixes smaller than /24.

BGP does not have a prefix "rejection" mechanism.
