It does sound as though you have a pair of Russian hybrids Kklofton, it would be an irresponsible pet shop if they mixed up litters let alone different species so I imagine what you were seeing as dwarfs all mixed up was a litter of Russian hybrids which can vary enormously in colour & some may look more like ww or campbells but they are still hybrids.

Good advice from velma about health & keeping pairs.
A good dwarf mix & natural treats is best for them, veg is fine but fruit is best avoided.

Look forward to seeing your two when you can post photos.
