Sorry no help with Emma Hardie.
But as for the Smashbox, I would email the company and explain. Tell them QVC UK said they cannot do anything about the missing brush. They should send you a free brush at the very least if they have good CS. Smashbox are now owned by Estee Lauder and everyone say they are good with any problems concerning their brands.
